I give you Evadne (As told by Pindar, that is. My poem is still in progress.) Now that I’ve found the Pindaric ode I was looking for, which seems to be the main source of this myth, aside from a tiny handful of much shorter references, I can finish and post it. In my search, I did find a rather interesting article of some linguistic analysis of this ode. (Unfortunately, this analysis comes in the form of a PDF article from JSTOR, which I’ve no license to distribute to the public.)

But now, for your reading pleasure, one of the not-so-well-known myths into which Apollo figures:

Pindar, Olympian Ode 6. 28 – 73 (trans. Conway) (Greek lyric C5th B.C.) :

“Today must we begone beside Eurotas’ stream, to journey . . . to Pitane. She [Pitane, eponym of the town], so they tell, was loved of great Poseidon, son of Kronos, and bore the babe Euadne, child of the crown of violet tresses, hiding the pains of maiden motherhood beneath her robe. But when the month was come of labour’s term, she sent her handmaids and bade them give the child for watch and ward to Eilatos’ hero son [Aipytos] at Phaisana, who ruled in Arkadia, and dwelt by Alpheios’ stream. There was the young babe nursed and grown, and by Apollon’s love first knew the touch of Aphrodite’s joy.

Yet could she not from Aipytos keep hidden through all her time the divine seed she bore. And he, struggling in bitter strain to hold within his heart a wrath unbearable, to Pytho straight departed, to seek a ruling of the oracle for this most grievous woe. But she laid by beneath a thicket’s shade her silvered urn, and she let fall her crimson girdle and bore a son, inspired of heaven. And to serve at her side Apollon, god of the golden locks, sent Eileithyia the kindly goddess, and the Moira (Fates) divine.

And from her body’s travail and the pains that were but sweet delight, was born Iamos, sped forth to the bright light of day. And she in her soul’s anguish left the babe there on the ground. But by the will of heaven there came to nourish him, with gentle care, the sweet and harmless venom of the bees.

Then came the king [Aipytos], riding in haste from rocky Pytho, and from all the household demanded of the child Euadne bore, saying he was begotten of Phoibos [Apollon], and should be beyond all others a peerless prophet for the race of man, and that his seed should last for ever. So he declared it to them. But all vowed they had not heard nor seen aught of the babe, the five days of his infant being. For in a deep brake had he lain concealed, a pathless waste, and o’er his tender limbs flowers of gold and purple splendour, pansies [i.e. violets, Greek ia] shed their rays upon him; thence was it his mother for all time proclaimed that he be called of men Iamos, this his immortal name.

And when he won youth’s joyous fruit, fair Hebe’s gleaming crown, he went to the midwaters down of Alpheios’ stream, and called aloud to the god of far-spreading might, Poseidon, his ancestor, and to the archer god ruler of heaven-built Delos, and this prayer he spoke, at night, beneath the starlit sky : that on his brow be laid the honour to be the shepherd of his people. Brief and clear called his father’s voice, answering `Rise my son, hence to the place where all men meet, bearing my bidden word.’

And they came to the lofty rock, where rules the high-throned son of Kronos [i.e. Zeus at Olympia]. There he gave him of the seer’s art this twofold treasure; first that he hear the voice that knows no lie; and when that Herakles, brave heart and hand, revered son of Alkides’ seed, should come to establish to his father’s name the feast where many a countless foot shall tread, with the ordinance of games and contests greatest of all [i.e. the Olympic Games], then shall the second honour, his oracle, high on the supreme altar of Zeus be set. Thus he ordained.

Thenceforth for all the sons of Iamos’ seed [i.e. the Iamides] through all Hellas their race holds high renown; and fortune’s day attended them; to deeds of noble grace paying due honour they tread their way of light.”
