Gaius Julius Hyginus
Perhaps trying to reconcile these conflicting accounts, Apollonius of Rhodes says that Crataeis was another name for Hecate, and that she and Phorcys were the parents of Scylla. Likewise, Semos of Delos says that Crataeis was the daughter of Hecate and Triton, and mother of Scylla by Deimos. Stesichorus (alone) names Lamia as the mother of Scylla, possibly the Lamia who was the daughter of Poseidon, while according to Gaius Julius Hyginus, Scylla was the offspring of Typhon and Echidna.
