The month name Ἀγαγύλιος is attested in Thessaly and Achaia Phthiotis. Recently, excavations at a Thessalian temple of Apollo in Pythion, at the foot of Olympus, have brought to light numerous ex-votos dedicated to Apollo, Poseidon and to an Artemis whose epiclesis is Agagylaia. Neither the month name nor the epiclesis, which is certainly to be connected with the month name, has yet received an explanation.
