Apollodorus of Athens

“After he had fashioned men from water and earth, Prometheus also gave them fire, which he had hidden in a fennel stalk in secret from Zeus.”

“When the gods had defeated the Giants, Ge, whose anger was all the greater, had intercourse with Tartaros and gave birth to Typhon in Cilicia. He was part man and part beast, and in both size and strength he surpassed all other children of Ge. Down to his thighs he was human in form, but of such immense size that he rose higher than all the mountains and often even scraped the stars with his head. With arms outstretched, he could reach the west on one side and the east on the other; and from his arms there sprang a hundred dragons' heads. Below his thighs, he had massive coils of vipers, which, when they were fully extended, reached right up to his head and emitted violent hisses. He had wings all over his body, and filthy hair springing from his head and cheeks floated around him in the wind, and fire flashed from his eyes. Such was Typhon's appearance and such his size when he launched an attack on heaven itself, hurling flaming rocks at it, hissing and screaming all at once, and gushing mighty streams of fire from his mouth. Seeing him rush against heaven, the gods took flight to Egypt, and when they were pursued by him, transformed themselves into animals. While Typhon was still at a distance, Zeus pelted him with thunderbolts, but as the monster drew close, Zeus struck him with an adamantine sickle, and then chased after him when he fled, until they arrived at Mount Casion, which rises over Syria. And there, seeing that Typhon was severely wounded, he engaged him in hand-to-hand combat.”
