 In the Book of Jonah, a worm (in Hebrew "tola'ath", "maggot") bites the shade-giving plant's root causing it to wither; whereas in the "Epic of Gilgamesh", Gilgamesh ties stones to his feet and plucks his plant from the floor of the sea.Once he returns to the shore, the rejuvenating plant is eaten by a serpent.Campbell also noted several similarities between the story of Jonah and that of Jason in Greek mythology.
