 The Greek rendering of the name Jonah is "Jonas", which differs from "Jason" only in the order of sounds—both "o"s are omegas suggesting that Jason may have been confused with Jonah.Gildas Hamel, drawing on the Book of Jonah and Greco-Roman sources—including Greek vases and the accounts of Apollonius of Rhodes, Gaius Valerius Flaccus and Orphic Argonautica—identifies a number of shared motifs, including the names of the heroes, the presence of a dove, the idea of "fleeing" like the wind and causing a storm, the attitude of the sailors, the presence of a sea-monster or dragon threatening the hero or swallowing him, and the form and the word used for the "gourd" (kikayon).Hamel takes the view that it was the Hebrew author who reacted to and adapted this mythological material to communicate his own, quite different message.
