 The Apollonius scholia refers to a ""Gigantomachia"" in which the Titan Cronus (as a horse) sires the centaur Chiron by mating with Philyra (the daughter of two Titans), but the scholiast may be confusing the Titans and Giants.Other possible archaic sources include the lyric poets Alcman (mentioned above) and the sixth-century Ibycus.The late sixth early fifth century BC lyric poet Pindar provides some of the earliest details of the battle between the Giants and the Olympians.
