Pytho

Greek myth gives Pytho as the serpent or dragon that guarded the sanctuary at Delphi before Apollo claimed the site for his own oracle, born of the earth goddess Gaia and dwelling in the chasm or spring at the foot of Mount Parnassus. Sources differ on the creature's gender and on its role before Apollo's arrival: some accounts give a male serpent, Python, that simply guarded the place and its earlier oracle, while others give a female drakaina, sometimes named Delphyne, sent by a jealous Hera to hunt down Apollo's mother Leto during her pregnancy.

The central episode is stable across the tradition even where the creature's background varies: soon after his own birth, Apollo travels to Delphi and kills the serpent with his arrows, in most versions after a pursuit or a direct confrontation at the site. He then takes the sanctuary and its oracle as his own, is credited with founding the Pythian Games in commemoration of the victory, and the priestess who thereafter speaks the oracle's utterances takes the title Pythia from the same root. Later mythographers, including the summary of Greek myth transmitted under Apollodorus's name, present the killing as the founding act that makes Delphi Apollo's place rather than an incidental battle.

Antiquity itself explained the name as coming from a verb meaning "to rot," tied to a tradition that the serpent's body was left to decay where it fell. The same root produces a small family of related terms — the priestess's title Pythia and Pythios as a cult epithet of Apollo as the serpent's slayer — which properly belong to Apollo and his oracle rather than standing as alternate names for the dragon itself, though reference works sometimes group all of them under one headword. Comparative surveys of dragon-slaying and serpent-guardian myths worldwide, including Bantu material that occasionally cites Pytho alongside other traditions' serpents, treat it as one example among many rather than as evidence of any shared origin.

Read as a personality, Pytho comes across as a fixed, ancient presence rather than an aggressor by disposition — in the strand where it simply guards the place, it acts on custodial instinct rather than malice; in the strand where it is sent after Leto, it acts as an agent carrying out someone else's grudge rather than pursuing one of its own. Either way, the myth allows it very little independent will: its entire narrative function is to be the obstacle whose defeat legitimizes Apollo's claim to Delphi, so it reads as a fixture belonging to the place more than as a character pursuing any aim of its own.
