With the arrival of spring and its attendant weather foibles and whims, rainbows have been on my mind. Most immediately, leprechauns attending their pots of gold at the end of the rainbow arrived in March. They have come posing as decorative items or on greeting cards to remind us of the Celtic heritage that has so influenced the cultures wherever the children of Danu have made their homes.

My youngest daughter and I once saw the gleaming gold at the end of the rainbow. True story. We were driving uphill along the freeway towards the mountains that form the backdrop of the valley where we live. A dramatic scene of dark clouds dropping rain along the ridges was suddenly pierced by sunlight. An intensely bright rainbow appeared, and seemingly ended on the highway ahead of us. At that moment, there was a burst of golden light off of the wet pavement ahead of us that caused both of us to exclaim out loud in surprise and wonder. We both immediately thought of the “pot of gold” and decided to believe that we had been witness to its actuality. Of course, as is the nature of this sort of ephemera, it was gone in a flash.
Quite a few years later, when my daughter got her first driving permit, we took to the open highway on a road trip to give her a chance to practice driving. We saw a rainbow the very first night out about sunset, at Kingman, Arizona, blazing across a blue-black bank of clouds. We continued to see them all through our journey to the Grand Canyon and Sedona. For some reason rainbows in the desert are more sharply vivid than those in more humid climes. The rain, such as it is, hangs like veil wafting on some high-blown breeze, the drops of water not even reaching the ground. Then the rainbow leaps into sight, often accompanied by a second arc, the mirror reflection of the original. We still refer to that vacation as “the rainbow trip”, a young and happy time for mother and a daughter in transition, taking that early step towards adulthood.
Rainbows in mythology are a worldwide leit motif, and like most mythological elements, they are viewed with joy in some cultures, but with dread in others. In looking over the rather vast amount of material that is out there on the internet about the mythology of rainbows, I was drawn to the mythological figure of Iris, the ancient Greek goddess of the rainbow. Perhaps it was because the purple iris are coming up in my garden now, or maybe it was because this goddess has remained throughout the ages as recognizably herself. After the decline of the ancient Greek civilization, she continued to be known as “Iris” during the successive centuries of the Roman Empire’s rule. Unlike other Greek gods and goddesses, she did not suffer any name change.
With the restoration of classical learning during the Renaissance, she reappeared in literature and art still called by that name, “Iris”. In modern Spanish the rainbow is still called arco iris, “Iris’ bow”. And in English, the word “iris” was given to the flower that thrusts its proud spear-shaped leaves and richly-hued blooms up from the earth in spring. Her name is also memorialized as the colored part of an eye. So one could say that the rainbow is both the band of colors we sometimes see after a rain and also a part of what we see it with.

What is left of Iris’ mythology is fragmentary and incomplete. But there are intriguing bits that can send the mind into a reverie. This golden-winged goddess, according to Hesiod, is daughter of the sea god Thaumas and his wife Elektra (the goddess, not the queen). Her father’s name has given rise to the word “thaumaturgy”, meaning “miracle-working”. The Roman poet,Virgil, sometimes called this goddess “Thaumantias”. That designation continued to be used in some medieval literature. Her mother’s name, “Elektra”, translated “bright one”, denotes the sparkle which is so necessary for the rainbow to manifest. After all, it is the sudden beaming of sunshine through raindrops that creates the prism of colors that tint Iris’ robes.
Iris announced herself to mariners after squalls passed and must have been a welcome sight to them. No doubt many an ancient mariner felt his life had been miraculously spared after the storm had abated. Lord Byron wrote on just such a theme in Don Juan, Canto II.
“Now a rainbow, bursting through
The scattering clouds, shone, spanning the dark sea…
The airy child of vapour and the sun,
Brought forth in purple, cradled in vermilion,
Baptized in molten gold and swathed in dun…
Our shipwrecked seamen thought it a good omen;
It is as well to think so now and then.
“Twas an old custom of the Greek and Roman,
…and so this rainbow looked like hope,
Quite a celestial kaleidoscope.”

However, like many families, Iris has its more difficult members. Her sisters are the Harpies, those entities that bedevil and even drive insane those who offend the gods. (A reminder that the dark is closely related to the light.) The Harpies beset the wrong-doer with endless tormenting thoughts arising from a guilty conscience.
In the earliest writings in which Iris is mentioned, she acts as messenger of the gods. She is either the personification of the rainbow itself, or the rainbow is the bridge which she traverses from heaven to earth, or from heaven to under the sea and back again. She carries out this duty for centuries before Hermes (Roman Mercury) ever comes on the scene.
In the Iliad of Homer she is busy carrying messages back and forth to both the Achaen Greeks as well as to the Trojans because the gods and goddesses took sides in that epic conflict. However, in the Odyssey it is Hermes alone who traverses heaven to earth with divine instructions for mortals. By the time the Roman poets add their mythical musings to tales of gods and goddesses, Iris has become the exclusive messenger of Juno, while Mercury carries Jupiter’s (Jove’s) words from on high.

One of the mentions that Homer made of Iris depicted her in the role she plays in saving the goddess of love and beauty, Aphrodite. Aphrodite’s own mortal son, Aeneas, had been wounded on the battlefield of Troy, so the goddess sped to his side to save his life. But in so doing, she herself was wounded in the hand. Zeus, seeing this, dispatched Iris to bring the lovely Aphrodite back to Olympus to the seat of Ares, where she could recover. Once she did so, she borrowed the war god’s chariot, and with Iris at the reins, she traveled to Hera, to seek revenge.

Perhaps today, for those of us who view the ancient stories as maps to the human psyche, this imagery of Iris rescuing Aphrodite seems to offer the possibility that after some terrible wounding, an appreciation of beauty and the ability to love again can be restored. On the other hand, Aphrodite seeks revenge, so the tale goes. And who doesn’t know this side of the goddess, when she becomes Nemesis? Thus, the story, while hopeful, is also cautionary. Notice that either choice is aided by Iris. It would seem that it’s up to us to choose, but to choose carefully. One shouldn’t forget the proximity of the Harpies.
Although the Trojans, whom Aphrodite favored, lost the war, Aeneas was one of the survivors who escaped, along with a number of Trojan women. In the Aeneid, Virgil, the Roman poet, tells the tale of how Aeneas made his way wandering across the Mediterranean to arrive eventually at the Tiber River, thus becoming a founder of Rome.
And of course, Aphrodite, his mother, became revered as Venus to the Romans, remaining to this day the holder of her archetypal throne. Iris’ key role then, seems to have been to save and serve the Great Goddess by restoring her to her divine place on Olympus where she remained, even as civilizations rose and fell.

Iris also plays a role in the Aeneid. By the time Virgil wrote his epic poem, Iris had become the exclusive messenger of Juno, queen of the Roman pantheon. In one episode, a storm drives the Trojan ships to shore in Sicily. The tomb of his father, Anchises, was located there. According to custom, Aeneas was obliged to give offerings in memory of his father. Having made those offerings, a large and unusual serpent, multi-colored as the rainbow, emerges to receive them. Virgil describes the coloring of the friendly reptile:
“More various colors thro’ his body run,
Than Iris when her bow imbibes the sun.”
This imposing creature probably should have been understood as a representative of the great mother goddess, who for millennia had been thought of as the source of life, death and rebirth. But Aeneas, after being shown this boon, dedicated the prescribed funeral games to Jove (Jupiter) rather than to Juno, as he should have. Juno, incensed at this slight to her august dignity, sends Iris, disguised as an old woman, to the Trojan women. Her message is that they should burn Aeneas’ ships and travel no further.

Since the women were very weary of wandering, they were willing to consider this option. When the old woman’s subversive activities were found out, she rose into the air as her true self, a brilliant, glowing rainbow. The Trojan women then decided that they must do as Juno had instructed. They managed to set fire to four ships of the fleet before Juno’s plan was thwarted by Jupiter, who sent rain to put out the fires.
This story fascinated me for a couple of reasons. One is the mention of the rainbow-colored serpent. We know that up until today in Australian aboriginal lore, the rainbow serpent is the primal creatress deity. Of course, Virgil would not have known that mythology, but the same motif was widespread among African peoples. This serpent in the Aeneid then must be a link to one of the oldest of rainbow myths, wherein the rainbow goddess/serpent is the source of all creation. Was it simply intuited by Virgil, or had he heard such folklore from Africans living in Rome?

It brings up a seminal debate. Do myths, which show so many similar patterns across the world, proceed from a single original group of humans who lived at an unfathomably distant past time, or do such universal images and themes exist somehow hardwired into human imagination, forming the basis of a collective unconscious? Carl Jung believed the latter theory to be true and developed his psychology of the archetypes based upon it.
Then there is the fact that Aeneas purposefully changed the tradition of dedicating the funeral games to the mother/queen goddess, choosing instead to offer them in honor of the father/king god. This reference seems to underpin a theory that the cycle of stories regarding the Trojan war were a chronicle of the time in prehistory when humans’ concept of the ruling divinity shifted from a feminine image to a masculine one–from Mother God to Father God. Iris’ role as the old wise woman seems to hint at an older order of service to the Great Goddess that was antagonistic to what was then a coming “new world order”.
In our time of paradigm shifts, such hints about this change that occurred at the dawn of history stir the imagination. We are invited to more deeply understand the duality at play within our own psyches–a synergy of opposites which is also writ large in the history of humanity. From D.H.Lawrence’s The Rainbow (1915) comes the following passage. The heroine has a vision of a new world when she sees a rainbow above a gloomy “dun atmosphere over the blackened hills”, a landscape made ugly by human industry:
…She saw in the rainbow the earth’s new architecture, the old brittle corruption of houses and factories swept away, the world built up in a living fabric of Truth, fitting to the over-arching heaven.”

The Rainbow by Robert Delaunay, 1913
Returning to stories from antiquity, Ovid recounted one in which Iris carried a message from Juno, Roman queen of the Gods, to Morpheus, god of sleep. (When a double rainbow appeared, the second, darker or paler one, the mirror image of Iris, was associated with Morpheus.) Ovid told of her visit to the realm of the unconscious, dreaming mind in his Metamorphoses. “So Iris, in her thousand-colored mantle, a rainbow through the sky, sought out the palace under the cloud, the royal home of Sleep…”

Morpheus and Iris
by Pierre Guerin
The poet goes on to describe how she made her way to where Morpheus dwelt: “The maiden goddess entered, using her hands to part the dreams, to clear her way, and the shining of her garments brightened the holy home, and the god saw her… And, her instruction given, Iris left him…and she soared upward along the rainbow arch she had descended.”
In this way Ovid pictures mythically how it is that we sometimes receive messages that come from the depths of the unconscious. Iris with her full spectrum of differentiated light may enter even into the house of Sleep. Thus, we can understand Iris as the bringer of dreams of portent, especially those dream images that sometimes arise in brilliant technicolor, the ones that linger and cause us to ponder their meaning.
Although Ovid calls Iris a “maiden goddess”, in other stories she was married to Zephyros, the gentle breeze, and their child was Eros himself, or perhaps one aspect of him, “Pothos”, meaning “desire”. This story earned Iris the title of “mother of love”. But that is surely a conflation of the messenger with the source of the message, Aphrodite, who is more often depicted as the mother of Eros (Cupid to the Romans). And then we must also consider Hesiod, writing much earlier, who imagined Eros springing from Chaos, thus beginning the mutual attraction of one thing to another so that perceived reality could come into form. So while some poets have given Iris this title, it is a contested one. Eros is not easily confined to a single mythic geneology.
So what are we to make of Iris today with our modern, scientifically-informed views? We know that the rainbow results from the refraction of sunlight through water drops. We know that the colors we perceive are the differentiation of the light spectrum in the range visible to the human eye. The poet Keats took exception to the scientific view being the exclusive way of seeing this natural phenomenon. He complained that Newton had “destroyed the poetry of the rainbow by reducing it to a prism“. He wrote the following lines:
“Philosophy will clip an angel’s wings,
Conquer all mysteries by rule and line,
Empty into the haunted air, and gnomed mine–
Unweave a rainbow.”

Light passing through a prism.
Refraction varies by frequency.
But Emily Dickinson seemed less worried that science could ever explain the inspirational message that a rainbow can still carry:
“We shall find the cube of the rainbow,
Of that there is no doubt;
But the arc of a lover’s conjecture
Eludes the finding out.“
And Percy Bysshe Shelley proclaimed the enduring power of Iris as muse to a writer in the following lines:
“The triumphal arch through which I march,
With hurricane, fire, and snow,
When the powers of the air are chained to my chair,
Is the million-colored bow;
The sphere-fire above its soft colours wove,
While the moist earth was laughing below.“

In addition, Lucy Larcom in 1824 in her work Three Old Saws suggested that we ourselves have some role to play in carrying along Iris’ message. She wrote:
“If the world’s a vale of tears,
Smile till rainbows span it!“
So as I write this, on this day and night of the vernal equinox, 2013, Iris is ’round about. She is making an appearance right now as the flower named in her honor, growing in spring gardens.

She is coloring our eyes while suggesting that we pay attention to the many-nuanced perceptions that her waves of light can bring to us. The full spectrum of awareness is her gift. And she is hiding behind dark clouds, ready to jump forward waving the banner of peace between heaven and earth as soon as a storm passes. She is undimmed and un-discouraged by all the strife here below–quite undeterred by resolute claims that she is merely a wholly explainable trick of the light as it passes through water drops. William Wordsworth spoke for Iris’ enduring enchantment when he wrote:
“My heart leaps up when I behold
A rainbow in the sky:
So it was when my life began;
So is it now I am a man;
So be it when I shall grow old.
Or let me die!”

Hopefully, we will all remain as excited about rainbows as Wordsworth was. Happy Spring!
