(Δελφινία), a surname of Artemis at Athens. (Pollux, 10.119.) The masculine form Delphinius is used as a surname of Apollo, and is derived either from his slaying the dragon Delphine or Delphyne (usually called Python) who guarded the oracle at Pytho, or front his having shewn the Cretan colonists the way to Delphi, while riding on a dolphin or metamorphosing himself into a dolphin. (Tzetz. ad Lycoph. 208.) Under this name Apollo had temples at Athens, Cnossus in Crete, Didyma, and Massilia. (Paus. 1.19.1; Plut. Tiles. 14; Strab. iv. p.179; Müller, Aeginet. p. 154.)
