Castalius was either a simple mortal, or a son of Apollo and father of Delphus, who came from Crete to Crissa, and there founded the worship of the Delphinian Apollo.1 Another account makes Castalius a son of Delphus and father of Thyia.2 A well at the foot of Mount Parnassus might be named for him (see Castalia).
