Boyle’s Law, Cartesian diver

Tonight is chem lab night for Susanna and two friends. Our ordinary lab manual is excellent, but the lab for Boyle’s Law seemed far too complicated to reinforce the concepts involved, and it lacked illustrations to make clear the relation of the procedure to the principles at work. So on the fly, we changed gears, and decided to demonstrate the volume-pressure relationship of Boyle’s law with a Cartesian diver. The girls, along with Jackson, their comrade cousin in Missouri who joins us by video chat, began by searching youTube for “Boyle’s Law” and for “Boyle’s Law, Cartesian diver,” and then adapted the procedure to use a 2-liter bottle, a glass eye dropper and some food coloring. The diver made for a cool, kinesthetic demo of Boyle’s pressure-volume relationship for gases, and made an ideal segue for applying Boyle’s Law to “the bends.” Instead of a confusing lab that would have brought frustration while obscuring the principle, the result was a lot of thinking, learning and fun! See for yourself…

Our Passover

Tonight we’re grateful to celebrate Passover with some new friends, many of whom have not experienced it before.

Passover 2013
Passover, 2013

Since before our eldest daughter was old enough to remember, we have celebrated Passover together as a family. The tradition is now cherished, with fond memories, by all of us. It began in 1988, our second year of marriage, when a Messianic church held a seder, open to the public, at the local Denny’s. Candace and I eagerly seized on the opportunity to participate and learn more, and resolved to make a Messianic seder a regular tradition. Unlike some strands of Messianic Christianity, we were not motivated by any sense of obligation to biblical law; our conviction then as now was that there is one covenant of grace uniting both Testaments, and uniting Hebrew and Christian believers into one people of God. We saw celebrating Passover together and with our children not as an observance of law, but as a celebration of God’s grace through countless generations.

As a young Christian, I was much taken by books like Peter Gillquist, The Physical Side of Being Spiritual,, Francis Schaeffer, The New Super-Spirituality,, Udo Middelmann, Pro existence, Edith Schaeffer, Hidden Art, Hans Rookmaaker, Art Needs No Justification, or Ranald Macauley & Jerram Barrs, Being Human: The Nature of Spiritual Experience, all of which encouraged thinking about how God loves ordinary, physical and tangible things, and uses them to embody his presence with us. The Incarnation provides the paradigm for creation, and the sacraments are exemplary of his hidden presence with us through other people and all that he has made. For me, this longstanding interest in God’s presence mediated through creaturely life and physical things was part of the reason I wanted to better understand the Hebrew celebration of Passover. It also didn’t hurt that I was an avid reader of Francis and Edith Schaeffer’s other books, including Christianity is Jewish which taught me this poem: “How odd of God to choose the Jew. But odder still are those who choose the Jewish God and hate the Jew.” When their daughter, Susan Schaeffer Macauley, wrote a book on pedagogy, For the Children’s Sake, I was immediately attracted to the Charlotte Mason tradition it articulated, even before we had children of our own. As I’ve noted here before, Mason likewise emphasized the pedagogical value of direct and ordinary experience. So it seemed natural to us that a regular celebration of Passover would impart to our children, as well as to us, a deepened understanding of the one covenant of grace revealed in the Old and New Testaments.

Christians may expect many benefits from the celebration of Passover. Our children may learn what grace looks like in a multi-sensory, participatory manner, repeated throughout the short years of their lives with us. But even if we do not have children of our own, celebrating Passover may help us develop a greater sympathy toward our Jewish brothers and sisters, particularly in the post-Holocaust epoch in which we live, when the need to actively repudiate anti-Semitism remains an urgent imperative (sadly, even within some churches). And, in addition, experiencing this Hebrew tradition promises to provide us with a clearer understanding of our Lord, as we learn to see him through non-Latinized eyes:

“We put a Gentile mask on the face of Jesus…. We need to go to school with the People of Israel, as it were, in order to share with them the training they were given by God through many, many centuries until a matrix of understanding and thought and worship was prepared in Israel appropriate for the reception of God’s ultimate self-revelation in Jesus Christ.” Thomas F. Torrance, in The Witness of the Jews to God, ed. David W. Torrance (1982), p. 97.

After all, Jesus grew up celebrating Passover year after year, and chose that occasion for his own Last Supper. Any Christian’s understanding of the eucharist will surely be deepened by a greater appreciation of how the first disciples experienced Christ’s final Passover meal.

Practicalities

Rubin, Messianic Passover HaggadahIn figuring out the logistics for this new family tradition, we relied upon The Messianic Passover Seder Preparation Guide by Barry Rubin. For every participant around the table, we obtain a copy of Rubin’s Messianic Passover Haggadah to follow along with during the seder.

Because the meal is a major undertaking, we celebrate Passover at whatever time is most convenient for us during the month prior to Easter, so it has become a waymark on our Lenten journey. The Passover meal has become for us a part of spring in the same way that fall and winter wouldn’t be the same without Thanksgiving and Christmas dinner. When we were diagnosed with an allergy to gluten, Candace was not deterred, but quickly perfected the art of making gluten-free matzah and other Passover recipes!

Tips: Identify beforehand six readers, in addition to the leader and the child who asks the four questions. If a pastor is present, ask him or her to read the Leader texts from p. 27 through the top of p. 29 (the Cup of Redemption, after the meal). So that all may eat or drink together, mention at the beginning that the leader will indicate when to drink the cup or eat the matzah, since there are times when either might be poured or distributed and held a little while. Sometimes, to accommodate extra guests, we set up several tables where each table has its own seder plate, pitcher of grape juice, afikomen and ransom (a prize of chocolate or jelly beans for the children who recover the afikomen). Each table will need a designated “father” to point out items on the seder plate, pour the grape juice, etc., and a designated “mother” to light the candles.

—–

While reading Rubin’s edition of the Haggadah, I frequently insert the following additions. Page numbers are indicated for the 2005 revised edition. Quotations are from Rabbi Yechiel Eckstein, What Christians Should Know About Jews and Judaism (1984).

Page 3, before paragraph 1:
We begin by reciting the prologue of the 10 Commandments:
“I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery.” (Exodus 20:2)

Page 3, after paragraph 2:
“You shall tell your son on that day, ‘It is because of what the LORD did for me when I came out of Egypt.’” (Exodus 13:8)

“We retell the story and symbolically relive the events. We are to feel as if we ourselves were just delivered from Egyptian bondage… ‘For God did not redeem our ancestors alone, but us as well.'” (Eckstein, 96)

Page 3, after paragraph 4:
“The Pesach festival bears eloquent testimony that God hears the cries of the oppressed and redeems humanity. ‘And the people of Israel groaned under their bondage, and cried out for help, and their cry under bondage came up to God. And God heard their groaning, and God remembered his covenant with Abraham, with Isaac, and with Jacob’ (Exod. 2:23-24). Curiously, although Moses was the key figure in the exodus drama, his name is not mentioned even once in the entire Seder service. For we are not to confuse Moses, the divine instrument of God’s salvation, with God himself. It was God who heard Israel’s cries. It was he who interceded in history to redeem them.” (Eckstein, 103-104)

Page 5, top:
“Let all who are hungry come eat with us.” (Isaiah 55.1-3)

Page 8.
To save time, begin with the leader lifting the basin of water. Read the passage at the top of the page, from Psalm 24, while the basin is being passed. Add:
Only Messiah is clean and pure. Only Messiah can truly pray this prayer. Only through Messiah do we participate in worship together tonight.

Page 14, first sentence.
If other families are participating in other tables, change “I” to “the fathers”.

Page 16, (lifting the kharoset, the brown apple mixture).
The kharoset represents mortar:
“So they ruthlessly made the people of Israel work as slaves and made their lives bitter with hard service, in mortar and brick, and in all kinds of work in the field. In all their work they ruthlessly made them work as slaves.” (Exodus 1:13–14)

Page 17, before “Leader: The children of Israel…”:
“As we drink the wine, we recline slightly, as was the manner of Roman emperors, to demonstrate our freedom on this day. Even if we live under conditions of oppression, and are not in fact physically free, we are to feel as if we were. Pesach reminds us that true freedom also involves the inner, spiritual realm. It cannot be externally denied, nor can a condition of slavery and servitude be outwardly imposed. The physically oppressed must also recline and feel like emperors on Pesach night…. Nothing must stand in the way of fulfilling the mitzvah of feeling free on this holiday. (I have often marveled at how it was humanly possible for Jews living in concentration camps during the holocaust to fulfill this mitzvah of ‘feeling free’ on Pesach. And yet, the amazing testimony to the power of God’s spirit moving within humankind is that many Jews did find the spiritual strength and courage to fulfill it, despite their wretched conditions.)” (Eckstein, 101)

Page 21, within paragraph 1, after “…slavery of Egypt.”
“When your enemy falls, do not be overjoyed.” (Proverbs 24.17)

Page 24, after paragraph “Leader: Since the Temple…”
Jesus is our sacrificial lamb, sacrificed once for all for us.
“The next day he saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world!” (John 1:29)
“Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed.” (1Corinthians 5:7)
“He has no need, like those high priests, to offer sacrifices daily, first for his own sins and then for those of the people, since he did this once for all when he offered up himself.” (Hebrews 7:27)

Page 26, end:
Eat desert now also; no additional food after the afikomen.

Page 27, top:
If a pastor is present, ask him to read the Leader texts here through p. 29 (top).

Page 27, before first “Leader” paragraph:
“For there is one God and one mediator between God and humanity, the man Christ Jesus, who gave himself as a ransom for all humanity.” (1 Timothy 2.5)

Page 29, end:
Re Elijah: “It is also customary to pour a fifth cup of wine…. For centuries Jews have poured but not drunk from this fifth cup to symbolize that God’s promise for their return to their homeland remains unfulfilled. It came to be called ‘Elijah’s cup’ since, according to tradition, it is the prophet Elijah who will usher in the Messiah….” (Eckstein, 100)

—–

“And he took a cup, and when he had given thanks he said, “Take this, and divide it among yourselves. For I tell you that from now on I will not drink of the fruit of the vine until the kingdom of God comes.” (Luke 22:17–18)
“For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.” (1 Corinthians 11:26)

Under the Starry Skies of J.R.R. Tolkien and Robert Frost

Update: I’ve revised and expanded this presentation and post a bit in preparation for two talks tomorrow (3/5/13) at Norman North High School. Should be fun!
—–

Tonight I’m giving an informal presentation at the OKC Astronomy Club on the astronomy of Tolkien and Robert Frost. It is good to be invited back. Although one might discuss either writer and their love of the starry skies for days on end, this is just a little talk, not scholarly in nature, intended simply to encourage us all to read them again with an eye to their love for astronomy.

Download it here (pdf, 34 MB).

J.R.R. Tolkien

J.R.R. TolkienTo introduce Tolkien, I begin with Dante’s closing sentence of the Divine Comedy and a quote from C.S. Lewis distinguishing Medieval and Modern models of the cosmos. Lewis, a friend of Tolkien’s, was similarly a medieval scholar. Lewis owned and regularly used a backyard telescope, and frequently mentions in his letters the weekly configuration of planets and seasonal appearance of constellations. In a famous conversation with Tolkien, the two scholars agreed to write works of fiction that would recover aspects of the medieval sensibility for modern times.

I then move on to a few quotations from Tolkien, such as this one from a passage describing the weary trails of Mordor:

“Frodo sighed and was asleep almost before the words were spoken. Sam struggled with his own weariness, and he took Frodo’s hand; and there he sat silent till deep night fell. Then at last, to keep himself awake, he crawled from the hiding place and looked out. The land seemed full of creaking and cracking and sly noises, but there was no sound of voice or of foot. Far above the Ephel Dúath in the West the night sky was still dim and pale. There, peeping among the cloud-wrack above a dark tor high up in the mountains, Sam saw a white star twinkle for a while. The beauty of it smote his heart, as he looked up out of the forsaken land, and hope returned to him. For like a shaft, clear and cold, the thought pierced him that in the end the Shadow was only a small and passing thing: there was light and high beauty forever beyond its reach.” J.R.R. Tolkien, The Return of the King, Book VI, Ch. 2, “The Land of Shadow.”

To present the skies of Middle Earth, I share Rachel’s Song of the Stars poem because it represents Tolkien’s astronomy so well, and also in the hope that the beauty of a poem will attract his readers to the wonders of skywatching. To begin exploring Tolkien’s astronomy, start with the following:

  • Rachel’s poem, Lindë Elenion, “Song of the Stars”
  • Rachel’s commentary
  • The quotes from Tolkien in the presentation.
  • Jim Manning, “Elvish Star Lore,” The Planetarian, December 2003, pp. 14-22.
  • Various articles by Kristine Larson, including:
    • “A Definitive Identification of Tolkien’s “Borgil”: An Astronomical and Literary Approach.” Tolkien Studies 2 (2005): 161-70.
    • “Swords and Sky Stones.” Mallorn 44 (2006): 22-26.
    • “Myth, Milky Way, and the Mysteries of Tolkien’s Morwinyon, Telumendil, and Anarríma.” Tolkien Studies 7 (2010): 197-210.
    • “Tolkien’s Burning Briar: An Astronomical Explanation.” Mallorn 43 (2005): 49-52.
    • “Sea Birds and Morning Stars: Ceyx, Alcyone, and the Many Metamorpohses of Earendel and Elwing.” Tolkien and the Study of His Sources: Critical Essays. Ed. Fisher, Jason. Jefferson: McFarland, 2011. 69-83.
    • “An Elrond by Any Other Name.” Mallorn 53 (2012): 4-8.

Robert Frost

Poet robert frost in affable portrait axe slung over shoulderIn the section on Frost, I quote from a few of the poems listed below, with page numbers to the Library of America edition.

Robert Frost, Collected Poems, Prose & Plays
Library of America edition

  • A Star in a Stone-Boat, 162 (more)
  • The Star-splitter, 166
  • Fire and Ice, 204
  • Stopping by the Woods on a Snowy Evening, 207
  • The Freedom of the Moon, 224
  • Fireflies in the Garden, 225
  • Acquainted with the Night, 234
  • Canis Major, 239
  • On Looking Up by Chance at the Constellations, 246
  • Lost in Heaven, 269
  • The Lesson for Today, 318
  • A Loose Mountain, 327
  • The Literate Farmer and the Planet Venus, 335
  • Five Noctournes (Night Light, Were I in Trouble, Bravado, On Making Certain Anything has Happened, In the Long Night), 346
  • Astrometaphysical, 352
  • Skeptic, 353
  • Two Leading Lights, 354
  • Etherealizing, 358
  • Why Wait for Science, 359
  • Take Something Like a Star, 365

A great starting point for reading Frost is “The Star-splitter”:

“You know Orion always comes up sideways.

Throwing a leg up over our fence of mountains,

And rising on his hands, he looks in on me

Busy outdoors by lantern-light with something

I should have done by daylight, and indeed,

After the ground is frozen, I should have done

Before it froze….”

Frost believed that every town should have its own telescope. The humorous tale recounted in this poem illustrates how the presence of a telescope will change people, and entire communities, for the better.

For more on Robert Frost and astronomy, don’t miss Charles Laird Calia, “The Astronomy of Robert Frost,” Sky and Telescope 2005, v. 109, issue 4, pp. 50-53.

Epilogue

As noted above, I use a quote from C.S. Lewis, The Discarded Image, to contrast medieval and modern cosmologies. Tolkien and Frost can illustrate these two sensibilities, respectively. Admittedly, this is an oversimplification, yet it’s a heuristic to prompt reflection. Their sensibilities are, of course, different, and I hope that I’ve indicated something of that in the presentation. Yet, just as with any collection of amateur astronomers gathered under a starry night, their evident similarities are more significant:

  • both Tolkien and Frost shared a common wonder toward the night sky.
  • A regular reader of either Tolkien or Frost sooner or later will be stimulated to watch the starry heavens.

For these and other reasons, I love them both.

I NÚMENNA, discovered by Rachel Folmar

Previous posts: | Lindë Elenion, Song of the Stars | Middle Earth astronomy |

One evening years ago, near bedtime, Candace and I were surprised when Rachel came down from her room where she had been hard at work on some project known only to herself. For homeschool that year, Rachel’s language arts course was an introduction to linguistics and historical philology based upon Quenya, one of the ancient Elvish languages recovered by the lifelong work of J.R.R. Tolkien. Rachel then began to sing “Into the West” to us, in Elvish, as movingly as Annie Lennox’s rendition in English (English lyrics here). Rachel somehow discovered the original Quenya version of the song, which Peter Jackson et al. must have had translated into English for their cinematic version of The Return of the King. We have no video of Rachel singing this original Elvish version, but Annie Lennox’s English version is at YouTube and Into the West - The Lord of the Rings - The Return of the King (Soundtrack from the Motion Picture).

Note: My daughter Rachel made this Quenya translation of “Into the West” many years ago and posted it on her homepage.mac.com website. Since that service went away this past July, I’m reposting some of that content here, along with some drawings that she made around the same time. Cf. the previous two posts. Check out Rachel’s current blog, Onward Into Light. “Into the West” has been mentioned on this blog previously here and here.

Translated into English, as sung by Annie Lennox:

Lay down your sweet and weary head
Night is falling, you have come to journey’s end
Sleep now and dream of the ones who came before
They are calling from across the distant shore

Why do you weep?
What are these tears upon your face?
Soon you will see all of your fears will pass away
Safe in my arms, you’re only sleeping

What can you see on the horizon?
Why do those white gulls call?
Across the sea a pale moon rises
The ships have come to carry you home

Dawn will turn to silver glass
A light on the water, all souls pass

Hope fades into the world of night
Through shadows falling out of memory and time
Don’t say we have come now to the end
White shores are calling, you and I will meet again
And you’ll be here in my arms, just sleeping

What can you see on the horizon?
Why do those white gulls call?
Across the sea a pale moon rises
The ships have come to carry you home

And all will turn to silver glass
A light on the water, gray ships pass
Into the west

Letter from the Dean: Rick Luce, “The Importance of Special Collections”

Originally posted at ouhos.org, the now-discontinued blog of the OU History of Science Collections. Neither this post nor any of its content should be taken as an official communication of the University of Oklahoma.


Living Library exhibit | iPad exhibit guide

LuceOne of the many attractions of the University of Oklahoma is the History of Science Collections. Upon my first visit, I felt an immediate excitement as I looked upon the handwritten notes of Galileo, the original letters of Charles Darwin, and countless other treasures from deep within the vaults. With extensive holdings that continue to grow, as documented in this Living Library exhibition and catalog, the History of Science Collections comprises an internationally-acclaimed center of excellence for exploring science and its history.

Ongoing growth in special collections is essential to the creation of a living library. As we witness the disruptive changes now underway with the emergence of eResearch, special collections become increasingly important as laboratories for scholarship which support knowledge creation both locally and in virtual space. They connect communities of scholars and students around the world in collaborative and multidisciplinary ways.

It is rare to see a special collection as embedded in academic programs as is OU’s History of Science Collections. Local users of the Collections include students representing every conceivable undergraduate major who are bridging and connecting different worlds, disciplines and paradigms for knowing and understanding. Students with a sustained interest in this multidisciplinary field of inquiry may opt to distinguish themselves by completing a minor or choose to earn a bachelors, masters or doctoral degree in the history of science.

In addition, the reach of the History of Science Collections extends internationally, attracting scholars from around the world each year whose on-campus visits contribute a vibrant dimension to ongoing academic conversations. The Collections also serves the international community by participating in digital projects that are transforming scholarship and research methods in the history of science. Many opportunities await us in collaborative ventures to create multidisciplinary, international eResearch communities at the intersection of the sciences and the digital humanities.

The History of Science Collections of the University of Oklahoma Libraries is a living library, and that means exciting prospects lie ahead.

Middle Earth astronomy, by Rachel Folmar

Previous post: | Lindë Elenion, Song of the Stars |
This post: | Commentary | Summary | Resources | Note |
| Next post: Into the West |

Read the full, uninterrupted text of the poem in the previous post. Commentary follows below, along with a summary of Middle Earth astronomy and a list of resources.

Commentary on Lindë Elenion, the Song of the Stars

by Rachel Folmar

(1) Even-time is drawing nigh
And in the fastly dimming sky
Bright Anor sinks her flaming head

Anor is the Sindarin word for the Sun, so this is describing a sunset.

And silver Ithil, round and fair,
Ascends once more the starry road
Of night, and mighty figures high.

Ithil is the Sindarin word for the Moon. You might remember both the words Ithil and Anor from the lands of Ithilien and Anórien in Gondor, and also from the cities of Minas Anor and Minas Ithil (which later became Minas Tirith and Minas Morgul). An interesting sidenote: Unlike many of the myths familiar to us, the Elves always referred to the Sun as a she and the Moon as a he. Mighty figures, a term I made up, refers to the constellations.

(2) The stars of hrívë, clear and bright

Hrívë is the Quenya word for winter. (See stanza #7 for summer.)

Surround the swordsman of the sky
Arrayed in silver and in blue
Upon his shoulder a scarlet jewel.
Menelvagil, Telumehtar fair,
Shakes his sword at the frostbit air.

This is talking about the constellation Orion, commonly known as Menelvagil in Sindarin, Menelmacar in Quenya, and sometimes referred to as Telumehtar. Most of the stars in this constellation are silvery or bluish (especially Rigel), except for the bright red star on his shoulder, Betelgeuse, perhaps known to the Elves as Borgil.

(3) And at his feet soars Helluin
Ice-blue fire flickering
A drop of water in a sea of stars
Yet ever bright with silver glow
As seen by Elves awakening
In Cuiviénen, long ago.

Helluin is the Elves’ word for the star Sirius in Canis Major. The name means ice-blue. It is the brightest star in the night sky, hence the words ever bright on line 4. In the very hour of the Elves awakening in Cuiviénen, the “blue fire of Helluin flickered in the mists above the borders of the world” (Silmarillion, Ch. 3).

(4) Still even then above his helm
Yet at his side Telumendil strode
Sky-friend holding two fair jewels
One of silver, one of gold.

It is not known for sure which constellation Telumendil is, but I suspect it to be Gemini from all the different clues I’ve found. Gemini is above and a bit to the left (east) of Orion. Its main stars are Pollux (a yellowish star) and Castor (silvery-blue). Telumendil, or Sky-friend, was put in the sky to be a companion to Orion, hence the phrase on line 2 “yet at his side.” Another little sidenote: Castor is very interesting. Through binoculars or a telescope it looks like three stars, but it is in fact six stars, all rotating around each other in an intricate dance!

Anarríma near them was set –
The golden crown of Elbereth.

Another unknown constellation. Anarríma literally means “sun-border.” It’s supposed to have been put in the sky as sort of a reflection of the Sun, and, like Telumendil, it was placed above Menelvagil. There are many speculations on what it could be, most notably Corona Borealis. However, Corona Borealis is pretty faint, and it’s anything but near Orion! So I prefer to think of Anarríma as the constellation Auriga, which is the only one near enough to Orion that could be seen as circular. It looks like a bright pentagon. Its main star, Capella, is the sixth-brightest star in the night sky, and even looks quite yellowish, as if it were a Sun-like jewel in the crown! For the word Elbereth, see the paragraph below.

(5) To hail the come of Menelvagil
Arise the Remmirath, the Netted Stars
Jewels blue as the sky by Anor’s light
Woven by Varda’s silver threads

The Remmirath are the Pleiades, a cluster of little stars that rises before Orion on a winter – or hrívë – night. They’re blue – as blue as the sky in the daytime, as it says in line 3. Varda is one of the Valar (or shall I say, Valier), probably the most important to the Elves. Known as Elbereth or Elentári (Star-Queen in Sindarin and Quenya, respectively), and also Gilthoniel (Star-Kindler in Sindarin, I think), she is the one who set the stars in their places.

A sentinel against the might
Of the bull from the east, and his scarlet eye.

The Pleiades are in the constellation Taurus the Bull. Tolkien didn’t write about Taurus as far as I know, so I’ve taken some artistic liberties here. I’ve never heard of a bull in Middle-Earth, but I thought that maybe they might live in the eastern lands. His scarlet eye is the red star Aldebaran. I suppose this line could hold sort of a double meaning for many of the free peoples of Middle Earth who lived when there was an ever-present threat from a certain Eye in the east.

(6) Ever swinging in the north
The Sickle of the Valar speaks
A mighty challenge to the dark
A sign of doom, a sign of hope.
The Wain, The Seven Butterflies
Valacirca reaps the fruit of the skies.

The Sickle of the Valar (Valacirca in Quenya) is what we know as the Big Dipper, in the constellation Ursa Major. This was a very important constellation, as it was put in the sky to be a challenge to Morgoth, a sign of doom to evil and of hope to Middle-Earth (Silmarillion Ch. 3). It is known by many names to the different people of Middle-Earth, most notably the Wain, or wagon, and the Seven Butterflies. “Ever swinging”: The Big Dipper is very close to the North Star, so it’s constantly above the horizon for those of us in the Northern Hemisphere. Hope never fades.

(7) And round the sickle lightly flying
Drinking the nectar of the night
In the north and east it flitters-
Wilwarin, the Butterfly.

Wilwarin is our constellation Cassiopeia, which looks sort of like a W or an M in the sky. It’s on the opposite side of the North Star from the Big Dipper. It’s also about the same distance from the North Star, so (depending on where you live, of course) it never really dips below the horizon.

Her counterpart in lairë soars
Soronúmë, the Eagle lord.

Lairë is Quenya for summer. Soromúmë the Eagle is another uncertain constellation. The simplest guess, and the most commonly accepted, is that it’s our Aquila the Eagle, a constellation that soars the skies in the summer (it lends it brightest star, Altair, to the Summer Triangle). Seems reasonable to me!

(8) And now the seven jewels most fair
Across the sky are wandering:

These are the planets, also known as the wandering stars.

Wat’ry Nénar and Luinil blue

Nénar and Luinil are probably Neptune and Uranus, though it’s not certain which is which. On the one hand, Neptune in Roman myths is the god of the sea, so that would make Nénar Neptune and Luinil Uranus, the god of the blue sky. Nénar is derived from nén, Quenya for water; and Luinil from luin, Quenya for blue. But on the other hand, the history of Middle-Earth isn’t infallibly connected to our old myths (though our myths were, as we all know, descended in many ways from Middle Earths long ago!). And judging by color alone, Neptune is definitely the bluer planet. So who knows…. Another thing: We can’t see Neptune and Uranus with unaided eyes, but this would have probably been no problem for the Elves and their keen eyesight!

Carnil, scarlet red as war

Carnil is Mars, the Red Planet (carnë is Quenya for red).

Elemmírë and clouded Lumbar,

Elemmírë (Lit. Star-jewel) and Lumbar (clouded or shadowy) are presumably Mercury and Saturn, respectively. Although it seems a bit strange to me that bright Saturn should be labeled shadowy. We could easily atone for this by pointing out that Saturn is a gas giant, so it’s obviously cloudy. But I doubt that even the Elves would be able to see that! So maybe Elemmírë is in fact Saturn (maybe the Elves perceived its ring?), and Lumbar is Mercury. But I really don’t know.

Alcarinquë, glorious star.

This is majestic Jupiter, brightest of all the planets except for Venus.

(9) And on the edge of night arising
The Mariner sails his glistening ship
Beyond the starlight journeying
Through shades of rose, and silver and blue
Eärendil bears the Silmaril
Star of Hope, and brightest of jewels.

The Star of Eärendil, brightest and most beautiful of all stars (and probably the most frequently mentioned!), is Venus. Eärendil the Mariner sails his ship Vingilot beyond the starlight, but he’s seen most often glimmering in the sunrise or sunset, as he comes back to Valinor. A Silmaril, brightest of jewels, is bound upon his brow. The sight of the star of Eärendil brought hope to the people, especially the Elves, of Middle-Earth. The story of Eärendil in the Silmarillion is really quite beautiful – read it if you haven’t already!

(10) When winter’s bite has met its night
And breezes warm from the sea are blown
A white swan lifts its wings to fly
And sails the stars to islands far
As sail the ships of Alqualond
Across the sea by Valimar.

One of my favorite constellations is Cygnus the Swan, and I couldn’t write any poem about the night sky without including it! Since as far as I know Tolkien didn’t record any Middle-Earth lore for the Swan, I made up my own. This constellation lifts its wings to fly in the summertime, right by Aquila the Eagle (otherwise known as Soronúmë). In fact, Cygnus’ brightest star Deneb is another star in the Summer Triangle. As for the last two lines: Alqualondë (literally Swan-haven), which I took the liberty of shortening to Alqualond for poetic reasons, is a port in Valinor. The ships there are shaped in the form of swans (the model for the ships of Lothlórien). Valimar, or Valmar (meaning Home of the Valar), is a city where many of the Valar lived. Though it is not right next to Alqualondë, it is easy for me to imagine the Elves, who longed to be in Valinor with the Valar, speaking of it so.

Middle Earth astronomy, summary

  • Arda: the Universe
  • Eä (literally the verb “to be,” “is”): the Universe or Solar System
  • Alcarinquë: Jupiter
  • Anar, Anor, Naira, Vása: The Sun
  • Anarríma (“Sun-border”): Possibly Auriga. Some speculation has been made that it might be Corona Borealis, but it is said that Anarríma was near Orion, and Corona Borealis isn’t. [Perhaps Sun-border refers to a constellation along the ecliptic, the path of the Sun, or near one of the equinox or solstice points.]
  • Borgil: Betelgeuse or Aldebaran
  • Carnil: Mars
  • Eärendil: Venus
  • Elemmírë (“Star-jewel”): Saturn or Mercury
  • elen, él, tinwë, nillë; gil, tim, tinw, êl: star

  • Luinil: Uranus or Neptune
  • Lumbar: Mercury or Saturn
  • Menelmacar, Menelvagil, Telumehtar (“Swordsman of the Sky”): Orion

  • Nénar: Neptune or Uranus
  • Remmirath (“Netted Stars”): The Pleiades
  • Valacirca (“Sickle of the Valar”), Cerch iM(b)elain, The Wain/Wagon, The Seven Butterflies: Big Dipper/Ursa Major
  • Soronúmë (“Eagle of the West,” I think): Possibly Aquila – is said to be in the west with outstretched wings
  • Telumendil (“Sky-friend”): Possibly Gemini – is said to be above Orion, set as a companion for him; or perhaps Boötes, containing the bright star Arcturus.
  • tingilyë, tingilindë: twinkling star
  • Wilwarin (“Butterfly”): Cassiopeia

Resources

I used these resources for the Song of the Stars:

DISCLAIMER: The purpose of this site is to help myself and others explore the depths and beauties of J.R.R. Tolkien’s incredible universe. By all means I do not know everything, and I’m sure there are many mistakes. If you have any comments and/or suggestions, feel free to email them to me.

Note: My daughter Rachel wrote this poem and commentary many years ago and posted them as pages on her homepage.mac.com website. Since that service went away this past July, I’m reposting some of that content here, along with some drawings that she made around the same time. Cf. Rachel’s current blog, Onward Into Light. For further reading on Tolkien and astronomy, a good place to start are some articles by Kristine Larsen (Rachel did not have access to these, as they were published after Rachel wrote her poem):

  • “A Definitive Identification of Tolkien’s “Borgil”: An Astronomical and Literary Approach.” Tolkien Studies 2 (2005): 161-70.
  • “Swords and Sky Stones.” Mallorn 44 (2006): 22-26.
  • “Myth, Milky Way, and the Mysteries of Tolkien’s Morwinyon, Telumendil, and Anarríma.” Tolkien Studies 7 (2010): 197-210.
  • “Tolkien’s Burning Briar: An Astronomical Explanation.” Mallorn 43 (2005): 49-52.
  • “Sea Birds and Morning Stars: Ceyx, Alcyone, and the Many Metamorpohses of Earendel and Elwing.” Tolkien and the Study of His Sources: Critical Essays. Ed. Fisher, Jason. Jefferson: McFarland, 2011. 69-83.
  • “An Elrond by Any Other Name.” Mallorn 53 (2012): 4-8.

Among other interesting tidbits, in these articles Larsen suggests that Elwing is Mercury (companion to Venus/Eärendil); Borgil is Aldebaran (not Betelgeuse); and Anarríma is Sagittarius (containing the most southerly point of the ecliptic, the location of the Sun at the Winter Solstice).

Lindë Elenion, by Rachel Folmar

Lindë Elenion, Song of the Stars

Even-time is drawing nigh
And in the fastly dimming sky
Bright Anor sinks her flaming head
And silver Ithil, round and fair,
Ascends once more the starry road
Of night, and mighty figures high.

The stars of hrívë, clear and bright
Surround the swordsman of the sky
Arrayed in silver and in blue
Upon his shoulder a scarlet jewel.
Menelvagil, Telumehtar fair,
Shakes his sword at the frostbit air.

And at his feet soars Helluin
Ice-blue fire flickering
A drop of water in a sea of stars
Yet ever bright with silver glow
As seen by Elves awakening
In Cuiviénen, long ago.

Still even then above his helm
Yet at his side Telumendil strode
Sky-friend holding two fair jewels
One of silver, one of gold.
Anarríma near them was set –
The golden crown of Elbereth.

To hail the come of Menelvagil
Arise the Remmirath, the Netted Stars
Jewels blue as the sky by Anars light
Woven by Vardas silver threads
A sentinel against the might
Of the bull from the east, and his scarlet eye.

Ever swinging in the north
The Sickle of the Valar speaks
A mighty challenge to the dark
A sign of doom, a sign of hope.
The Wain, The Seven Butterflies
Valacirca reaps the fruit of the skies.

And round the sickle lightly flying
Drinking the nectar of the night
In the north and east it flitters-
Wilwarin, the Butterfly.
Her counterpart in lairë soars
Soronúmë, the Eagle lord.

And now the seven jewels most fair
Across the sky are wandering:
Wat’ry Nénar and Luinil blue
Carnil, scarlet red as war
Elemmírë and clouded Lumbar,
Alcarinquë, glorious star.

And on the edge of night arising
The Mariner sails his glistening ship
Beyond the starlight journeying
Through shades of rose, and silver and blue
Eärendil bears the Silmaril
Star of Hope, and brightest of jewels.

When winter’s bite has met its night
And breezes warm from the sea are blown
A white swan lifts its wings to fly
And sails the stars to islands far
As sail the ships of Alqualond
Across the sea by Valimar.

Gold for old, blue for new
Nearly all of the works described in the Living Library guide were acquired since 1976, but occasionally they are compared with “golden oldies” acquired before that time. In that case, a gold color accent (perhaps as background to an image) emphasizes that an item is old (acquired before 1976). If two works are shown together on the same page, one old and one new (as pictured, below), then the “golden oldie” is indicated by gold and the new item (acquired after 1976) is marked by blue. When there are no color accents, then everything on that page is new.

The items displayed in this Living Library exhibit reveal how the History of Science Collections is a living library, growing constantly to serve a dynamic community of scholars.

As you view the books in this exhibit, look for the interweaving of two stories: the history of science, and the history of the Collections. Look for additional exhibit-related posts to appear on this blog over the next several weeks.

No appointment is necessary to view the exhibit. It will be available through the end of the semester. The exhibit is open during the regular hours of the History of Science Collections, which is located on the 5th floor of Bizzell Library. For accommodations on the basis of disability, call 405/325-2741.
