We will start on earth and travel upwards through the nine concentric spheres of the Ptolemaic system. We will follow the path of Dante and Beatrice in the Paradiso, looking for art motifs as we go.

The Ptolemaic system gave a geometric structure to the celestial world. In a later unit we'll see how linear perspective gave geometric structure to the terrestrial world.

Reading

The Ptolemaic Universe

God The Geometer

God the Geometer Slide 9-37: God the Geometer, Manuscript illustration.

Clark, p. 52

We vowed to search heaven and earth for geometric art motifs. We'll done a pretty good job on earth, so now lets try the heavens, and what better place to start than with God creating the universe. It almost seems like Medieval man thought he laid it out with a pair of compasses, a notion which may be due to a passage from the Old Testament:

"When he established the heavens I was there:

when he set a compass upon the face of the deep:"


The Four Realms

Lets look at a Medieval version of the universe, consisting of the Four Realms that we mentioned in our unit on number symbolism. Now lets group them into two sets of two;

 Two below the moon, or sublunary:  Matter
   Nature
 and two above the moon, or Translunary:  Celestial:
   Super-celestial


The Nine Spheres of Heaven
Giovanni di Paolo, Creation of World and Expulsion from Paradise Slide 10-2: Giovanni di Paolo, Creation of the World & Expulsion from Paradise,1445

Fisher, Sally. The Square Halo. NY: Abrams, 1995. p. 14

We now further divide the celestial realm into the 9 spheres of the heavens, the sun, moon, 5 planets, the fixed stars, and the primum mobile, and we get the geocentric universe shown in this picture by Giovanni di Paolo. It shows:

The Earth (brown) at center, shown as a Mappamondo, or world map, surrounded by the three other elements, water, air, and fire, its bright red clearly marks the boundary between the sublunary and translunary realms. Then comes the moon and planets, all blue, except for the Sun, yellow-white, with gilded sunburst, and Mars, in pink, for the red planet. Then the fixed stars with signs of the zodiac, the Primum mobile (the first moved) which regulated the motion of all the spheres beneath it, and the Empyrean heaven, the home of God and the angels.

The number of rings in pictures of this sort vary from one to the other. For one thing, theologians couldn't decide whether the empyrium occupied a definite sphere, or whether it was infinite and unknowable - a big problem for artists.

Di Paolo shows no ring for the Empyrium, just a region beyond the last ring, implying it can't be contained by a circular boundary.


Sacrobosco's Sphaera mundi:

Illustration from Sacrobosco Slide 10-7: Illustration from Sacrobosco

Dixon, Laurinda S. Giovanni di Paolo's Cosmology. Art Bull. Dec. 1985, p. 604-613.

The probable source for di Paolo's picture and others like it was Sacrobosco's Sphaera mundi: a popular source for this information written in the 13th century and used at universities. It presented an elementary and introductory view of the universe, giving Greek cosmology with a Christian spin.

So we have what Edgerton calls the Geometrization of Heavenly Space, the counterpart of our geometritization of terrestrial space acheived with linear perspective, where all receding lines travelled obediently to a neat vanishing point at infinity. This is part of a world view ruled by a general conception of an orderly universe that God had created out of chaos, where, according to the Book of Wisdom, God had arranged all things according to Number, Weight, and Measure.


The Sublunary World

Lets take the Sphaera mundi as our road map for our journey, starting with a quick look at the sublunary realm before taking off for the cosmos.


Sublunary vs. Superlunary

Compared to the rest of the Medieval universe, our sublunary realm is not so great. We may think that earth being at the center of the is special and exalted, but things are just the opposite.

Listen to Tillyard;

. . . far from being dignified . . . the earth in the Ptolemaic system was the cesspool of the universe, the repository of its grossest dregs.. .

By the grossest dregs he probably means people.


Portrayal of Astrologers and Astronomers

Slide 101 Slide 10-101:

Bouleau, Charles. The Painter's Secret Geometry. NY: Harcourt, 1963. p. 78

Well, maybe we're the dregs of the universe, but we can still gaze at the heavens and wonder, and the astrologers and astronomers who do that have always been a popular art motif, as those in this medieval manuscript illustration.


Allegories to Astronomy

Raphael, Astronomy Slide 10-104: RAPHAEL, Astronomy

Edgerton, Samuel. The Heritage of Giotto's Geometry. p. 104

Artists also like to depict allegories to astonomy, which, we recall, is one of the Seven Liberal Arts, part of the quadrivium.

And of course, the armillary sphere, which we saw before in Plato's Timaeus, where he describes how the circular paths for the stars were formed by the creator.

"He cut the whole fabric into two strips,which he placed crosswise at their middle points to form a shape like the letter X; he then bent the ends round in a circle and fastened them to each other . . . to make two circles, one inner and one outer."


The Dome of Heaven
Kepler's model of the universe Slide 3-6: Kepler's Model of the Universe

Lawlor, p. 106

Another model of the heavens is that we've seen before is Kepler's nested Platonic solids, and another is the dome. In The Dome of Heaven, Karl Lehmann, who writes,

One of the most fundamental artistic expressions of Christian thought and emotion
is the vision of heaven depicted in painting or mosaic on domes . . .

The Nine Circles of Heaven

But enough of this murky sublunary world where the air thick and dirty. Lets have a space odessy to the translunary world where the ether is clear and pure, to the celestial and the super-celestial spheres, the nine circles of heaven.

Dante leaving the Earth Slide 10-15: DI PAOLO: Dante leaving the Earth

Pope-Hennessy, John. Paradiso. The Illuminations of Dante's Divine Comedy by Giovanni di Paolo. NY: Random, 1993. p. 74

On our trip lets follow in the footsteps of Dante and Beatrice, in his Paradiso, shown here leaving the earth for the moon.


Dante's Paradiso

Paradiso is one book of the Divine Comedy written by the poet Dante Alighieri (1265-1321). It was started about 1307 was completed shortly before his death. It is an allegorical narrative of the poet's imaginary journey through hell and purgatory, guided by Virgil, who is, to Dante, the symbol of reason.

Dante and Virgil. Slide 10-13: DELACROIX: Dante and Virgil

Clark, Kenneth, The Romantic Rebellion. NY. Harper, 1972. p. 202

Dante is guided through the circles of heaven by Beatrice, a woman he met in 1274, and whom he loved and exalted in La vita nuova (The New Life) and in Paradiso.

Dante and Beatrice Slide 10-12: Dante and Beatrice

Dante, The Divine Comedy. Ill. Gustave Doré. London: Cassell. p. 183



In each realm the poet meets mythological, historical, and contemporary personages, each symboliizing a particular fault or virtue, each receiving the appropriate punishment or reward. In his Paradiso he conceived of heaven as a gigantic rose, built of circular rings of light simialr to the rose window of a Gothic cathedral.


Nine Ranks of Angels

HILDEGARDED VON BINGEN: Nine Ranks of Angels Slide 10-8: HILDEGARDE VON BINGEN. Nine Ranks of Angels

Fox, Matthew, Illuminations of Hildegard of Bingen. Santa Fe: Bear, c 1985. p. 74

When we left the world of people we entered the realm of the angels, supposedly arranged in three ranks of three -- a triple trinity -- shown here in Hildegard von Bingen's Nine Ranks of Angels.



Lowest Heirarchy:

 Angels  Moon
 Archangels  Mercury
 Principalities  Venus

Middle Heirarchy:

 Powers  Sun
 Virtues  Mars
 Dominations  Jupiter

Upper Heirarchy:

 Thrones  Saturn
 Cherubim  Fixed Stars
 Seraphin  Emperian

This arrangement is from a sixth-century book, The Celestial Hierarchy, ascribed to the neoPlatonist known as the Pseudo-Dionysius. (This is not the fun Dionysius of Greek Mythology, the god of wine, orgies, Phallicism, and dorm parties.)


Circle 1. The Moon

The Illustrations for Paradiso



We'll look at two sets of illustrations for Paradiso; the ones in color are by the Sienese artist Giovanni di Paolo, done about 1445, and the monochrome etchings are by Gustav Doré, done in the 1900's. Occasionally we'll have illustrations of the same passage by the two artists, like these, where Dante and Beatrice converse with Piccarda dei Donati and the Empress Constanza, who broke their vows and thus occupy the lowest sphere of heaven.

Danati and Costanza Slide 10-17: Donati and Costanza

Dante, The Divine Comedy. Ill. Gustave Doré. London: Cassell. p. 182

Danati and Costanza Slide 10-16: DI PAOLO: Donati and Costanza

Pope-Hennessy, John. Paradiso. The Illuminations of Dante's Divine Comedy by Giovanni di Paolo. NY: Random, 1993. p. 76

We'll see that the di Paolo illustrations are generally more specific and more literal than Doré's. They refer to a specific passage in the allegory, while the Doré pictures can usually go anywhere in the story.


Cigoli's Immacolata

TIEPOLO: Immaculate Conception Slide 10-27: TIEPOLO: Immaculate Conception, 1767.

Fisher, Sally. The Square Halo. NY: Abrams, 1995. p. 53

A popular art motif featuring the moon is the Virgin standing on the moon, usually wearing a crown of stars.

And a great portent appeared in heaven, a woman clothed with the sun, with the moon under her feet, and on her head a crown of stars.

Notice the radiance coming from her body, showing her clothed in the sun.

CIGOLI: Immocolata Slide 10-25: CIGOLI' Immocolata

Edgerton, Samuel. The Heritage of Giotto's Geometry. p. 252

But we're particularly interested in this version, done in 1612 by Cigoli. Note the mandorla, the nine celestial circles, and the dome as a model of the heavens. But especially look at the moon. For the first time it is shown pock-marked.

Galileo's Moon Drawings Slide 10-26: Galileo's Moon Drawings

Edgerton, Samuel. The Heritage of Giotto's Geometry. p. 241



Why? It turns out that Cigoli was pals with Galileo. Quoting Panofsky,

". . . the painter, as a good and loyal friend [to Galileo] paid tribute to the great scientist by representing the moon under the virgin's feet exactly as it had revealed itself to Galleo's telescope -- complete with . . . those little . . . craters which did so much to prove that the celestial bodies did not essentially differ . . . from our earth.

This may not seem like a big deal now but it defied convention and church doctrine that showed the moon either as a crescent or as a perfectly smooth orb, perfect and flawless as the person standing on it.


Moon Gods & Symbols

CORREGIO: Diana Slide 10-18: CORREGIO: Diana

Of course, the moon had associations long before Christianity, like the moon goddesses Isis and Selene, and the triple goddess of the New, Full, and Old Moon, goddess of Birth, Love, and Death.


Angels

DELACROIX: Jacob Wrestling with an Angel Slide 10-11: DELACROIX: Jacob Wrestling with an Angel

Clark, Kenneth, The Romantic Rebellion. NY. Harper, 1972. p. 220

Note that the moon has the lowest kinds of angels who do the grunt work, TV series, sell cellular phones, and wrestling with earthlings like Jacob.


Circle 2. Mercury

Mercury Slide 10-35: Mercury

Pope-Hennessy, John. Paradiso. The Illuminations of Dante's Divine Comedy by Giovanni di Paolo. NY: Random, 1993. p. 87

Lets now head for Mercury, shown by di Paolo as a golden disk. Mercury, naked, stands surrounded by seven heavenly intelligences. Humanity, represented by the four youths, are being guided by both the Old and New Testaments.


Archangels

Mercury is the sphere that has the most interesting rank of angels, the archangels. There are only three, Raphael, Gabriel, and Michael. Raphael appears in the Old Testament Apocrypha Tobit, in some tale involving a fish, as in this drawing by Rembrandt.

Circle 4. The Sun
di Paolo Slide 10-42: DI PAOLO:

Pope-Hennessy, John. Paradiso. The Illuminations of Dante's Divine Comedy by Giovanni di Paolo. NY: Random, 1993. p. 102

Here Dante and Beatrice reach the sun, shown by di Paolo as a golden wheel sending golden rays to the landscape below. The Sun, located in the middle of the orbs, with three lesser above and three below, like the heart in the middle of the body, or a wise king in the middle of his kingdom.


Sun Gods & Symbols

Recall that the circle was often used to symbolize the sun, and that Sun worship is one of the most primitive forms of religion, with early man often distinguishing between the triad of rising, midday, and setting sun, like the three Egyptian sun gods; Horus, the rising sun; Ra or Rê, themidday sun; Osiris, the old setting sun.

For Jupiter we have another good comparison of the illustrations by Paolo and Doré. Here the souls of the Just Rulers form into an eagle symbolizing divine justice and imperial authority, and speak with a single voice from its beak.


Circle 7. Saturn

di Paolo Slide 10-57: DI PAOLO:Saturn

GOYA: Cronos devouring children Slide 10-56: GOYA: Cronos devouring Children

citation

On to Saturn, shown as an old man with a sickle. Saturn often represented father time because of the confusion between Chronos, the Greek word for time, and Kronos, the Roman for Saturn.

The sickle may represent the grim reaper, eventually mowing down every living thing, or the instrument he used to castrate his father Uranus. Saturn is often shown devouring his children, signifying that "sharp-toothed" time devours whatever he has created.


Circle 8. The Fixed Stars

di Paolo Slide 10-58: DI PAOLO: Stars

Pope-Hennessy, John. Paradiso. The Illuminations of Dante's Divine Comedy by Giovanni di Paolo. NY: Random, 1993. p. 145

As they rise to the fixed stars, Dante and Beatrice look back and see the seven planets beneath them; the sun, lower left, a scarlet figure in a flaming chariot, to the right the moon, Mars, Mercury, Jupiter, Venus, and Saturn, arranged by the days of the week.

We haven't seen any angels since we left the archangels. Each sphere has its own type, but they have not been depicted by artists. But here in the fixed stars we have the Cherubim, little babylike creatures. They are probably recycled classical putti .

Sometimes only winged heads are shown. Others are shown with several sets of wings, often in the shape of a cross.

We now come to the last sphere, the primum mobile, or first moved, the sphere which dictates the motions of the other spheres. Here it is shown by di Paolo as a ring of golden light framing a mappamondo in the center of which is the figure of Christ.

Dore Slide 10-79: MANTEGNA: Assention, showing seraphim

Campbell, Joseph, with Bill Moyers. The Power of Myth. NY: Doubleday 1988. figure 19

The angels assigned to this sphere by Dionysius are the seraphim, usually depicted like cherubim, but are red.


The Empyrium

di Paolo: Cosmic Rose Slide 10-82: DI PAOLO: Cosmic Rose

Pope-Hennessy, John. Paradiso. The Illuminations of Dante's Divine Comedy by Giovanni di Paolo. NY: Random, 1993. p. 177

We finally reach the Empyrian, the highest heavenly realm, supposed to be composed by a kind of sublimated fire, the uppermost Paradise, the heaven; the seat of God. The image that dominates the final Cantos of Paradiso is the cosmic rose, shown by di Paolo as an actual rose, with nine angels and the Trinity.

And in the very last paragraph of The Divine Comedy, at the end of this fantastic journey down to hell and back, and through purgatory, and up through the circles of heaven, what does Dante talk about? Beatrice? God? No. He talks aboutgeometry.

As the geometer who attempts to measure the circle
and discovers not . . . the principle he wants,
So was I at that new sight

I wished to see how the image conformed to the circle
[but] here my power failed,
but my desire and my will were revolved,
like a wheel that is evenly moved
by the love which moves the sun and the other stars.



So we end our journey to the heavens with love and with geometry; what more could anyone who loves math ask for?
