Drakaina (mythology) in the context of "Latinisation of names"

Delphi (/ˈdɛlfaɪ, ˈdɛlfi/; Greek: Δελφοί [ðelˈfi]), in legend previously called Pytho (Πυθώ), was an ancient sacred precinct in central Greece. It was the seat of Pythia, the major oracle who was consulted about important decisions throughout the ancient classical world. The ancient Greeks considered the centre of the world to be in Delphi, marked by the stone monument known as the Omphalos of Delphi. The term omphalos was the Greek word for "navel".

According to the Suda, Delphi took its name from the Delphyne, the she-serpent (drakaina) who lived there and was killed by the god Apollo (in other accounts the serpent was the male serpent (drakon) Python).

In Greek mythology, Delphyne (Greek: Δελφύνη) is the name given, by some accounts, to the monstrous serpent killed by Apollo at Delphi. Although, in Hellenistic and later accounts, the Delphic monster slain by Apollo is usually said to be the male serpent Python, in the earliest known account of this story, the Homeric Hymn to Apollo (6th century BC), the god kills a nameless she-serpent (drakaina), subsequently called Delphyne. According to the Suda, Delphi was named after Delphyne.

In Greek mythology Axius (Ancient Greek: Ἀξιός, romanized: Axios) is a Paeonian river god, the son of Oceanus and Tethys. He was the father of Pelagon, by Periboea, daughter of Acessamenus. His domain was the river Axius, now known as the Vardar, flowing in the ancient region of Macedonia.

The river god was an ancestor of Euphemus and his son, Eurybarus, the hero who slew the drakaina Sybaris.
