The Metamorphoses of Ovid Book VII Fable. 6
Jupiter, at the prayer of his son Æacus, transforms the ants that are in the hollow of an old oak into men; these, from the Greek name of those insects, are called Myrmidons.

“Stupefied by so great an outburst of misery, I said, ‘O Jupiter! if stories do not falsely say that thou didst come into the embraces of Ægina, the daughter of Asopus, and thou art not ashamed, great Father, to be the parent of myself; either restore my people to me, or else bury me, as well, in the sepulchre.’ He gave a signal by lightnings, and by propitious thunders. I accepted the omen, and I said, ‘I pray that these may be happy signs of thy intentions: the omen which thou givest me, I accept as a pledge.’ By chance there was close by, an oak sacred to Jupiter, of seed from Dodona,105 but thinly covered with wide-spreading boughs. Here we beheld some ants, the gatherers of corn, in a long train, carrying a heavy burden in their little mouths, and keeping their track in the wrinkled bark. While I was wondering at their numbers, I said, ‘Do thou, most gracious Father, give me citizens as many in number, and replenish my empty walls.’ The lofty oak trembled, and made a noise in its boughs, moving without a breeze. My limbs quivered, with trembling fear, and my hair stood on an end; yet I gave kisses to the earth and to the oak, nor did I confess that I had any hopes; and yet I did hope, and I cherished my own wishes in my mind. Night came on, and sleep seized my body wearied with anxiety. Before my eyes the same oak seemed to be present, and to bear as many branches, and as many animals in its branches, and to be trembling with a similar motion, and to be scattering the grain-bearing troop on the fields below. These suddenly grew, and seemed greater and greater, and raised themselves from the ground, and stood with their bodies upright; and laid aside their leanness, and the former number of their feet, and their sable hue, and assumed in their limbs the human shape.

“Sleep departs. When now awake, I censured the vision, and complained that there was no help for me from the Gods above. But within my palace there was a great murmur, and I seemed to be hearing the voices of men, to which I had now become unaccustomed. While I was supposing that these, too, were a part of my dream, lo! Telamon came in haste, and, opening the door, said, ‘Father, thou wilt see things beyond thy hopes or expectations. Do come out.’ I did go out, and I beheld and recognized such men, each in his turn, as I had seemed to behold in the vision of my sleep. They approached, and saluted me as their king. I offered up vows to Jupiter, and divided the city and the lands void of their former tillers, among this new-made people, and I called them Myrmidons,106 and did not deprive their name of the marks of their origin. Thou hast beheld their persons. Even still do they retain the manners which they formerly had; and they are a thrifty race, patient of toil, tenacious of what they get, and what they get they lay up. These, alike in years and in courage, will attend thee to the war, as soon as the East wind, which brought thee prosperously hither (for the East wind had brought him), shall have changed to the South.”

Footnotes:

105. From Dodona.]—Ver. 623. Dodona was a town of Chaonia, in Epirus, so called from Dodone, the daughter of Jupiter and Europa. Near it was a temple and a wood sacred to Jupiter, which was famous for the number and magnitude of its oaks. Doves were said to give oracular responses there, probably from the circumstance that the female soothsayers of Thessaly were called πελειαδαιA. Some writers, however, say that the oaks had the gift of speech, combined with that of prophesying.

106. Myrmidons.]—Ver. 654. From the Greek word μύρμηξ, ‘an ant;’ according to this version of the story.
