Python. In Greek mythology, Python was the serpent, sometimes represented as a medieval-style dragon, living at the center of the earth, believed by the ancient Greeks to be at Delphi.
   Python, sometimes written Phython, presided at the Delphic oracle, which existed in the cult center for its mother, Gaia, Earth, Pytho being the place name that was substituted for the earlier Krisa. Greeks considered the site to be the center of the earth, represented by a stone, the omphalos or navel, which Python guarded.
   Python became the chthonic enemy of the later Olympian deity Apollo, who slew it and took over Python's former home and oracle. These were the most famous and revered in the ancient Greek and Roman worlds.
   There are various versions of Python's birth and death at the hands of Apollo. In the Homeric Hymn to Apollo, now thought to have been composed in 522 BCE when the archaic period in Greek history was giving way to the Classical period, a small detail is provided regarding Apollo's combat with the serpent, in some sections identified as the deadly drakaina, or her parent.
   The version related by Hyginus holds that when Zeus lay with the goddess Leto, and she became pregnant with Artemis and Apollo, Hera was jealous and sent Python to pursue Leto throughout the lands, to prevent her from giving birth to the twin gods. Thus when Apollo was grown he wanted to avenge his mother's plight
