Pelopidas (16.4-16.5)

and behind the temple two springs burst forth with a wonderful flow of sweet, copious, and cool water. One of these we call Palm, the other Olive to the present day, for it was not between two trees,[*] but between two fountains, that the goddess Leto was delivered of her children. Moreover, the Ptoüm[*] is near, from which, it is said, a boar suddenly came forth and frightened the goddess, and in like manner the stories of the Python[*] and of Tityus[*] are associated with the birth of Apollo in this locality.

Most of the proofs, however, I shall pass over; for my native tradition removes this god from among those deities who were changed from mortals into immortals, like Heracles and Dionysus, whose virtues enabled them to cast off mortality and suffering; but he is one of those deities who are unbegotten and eternal, if we may judge by what the most ancient and wisest men have said on such matters.
