Chapter XXVI.—Metamorphoses.

“Hence there has now been added, that the poets also adorn the falsehoods of error by elegance of words, and by sweetness of speech persuade that mortals have been made immortal; yea more, they say that men are changed into stars, and trees, and animals, and flowers, and birds, and fountains, and rivers.  And but that it might seem to be a waste of words, I could even enumerate almost all the stars, and trees, and fountains, and rivers, which they assert to have been made of men; yet, by way of example, I shall mention at least one of each class.  They say that Andromeda, the daughter of Cepheus, was turned into a star; Daphne, the daughter of the river Lado, into a tree; Hyacinthus, beloved of Apollo, into a flower; Callisto into the constellation which they call Arctos; Progne and Philomela, with Tereus, into birds; that Thysbe in Cilicia was dissolved into a fountain; and Pyramus, at the same place, into a river.  And they assert that almost all the stars, trees, fountains, and rivers, flowers, animals, and birds, were at one time human beings.”
