Apollo

Greek god of music, sun and light, prophecy, poetry, medicine, archery, and protector of herds and flocks. Twin brother of Artemis.
Four days after his birth on the island of Delos in the Cyclades, according to a legend, Apollo decided he would take revenge on a serpent named Python who molested his mother while she was pregnant. Python guarded the Oracle at Delphi and was the son of Gaia (Earth). The Oracle, at the time, was in the possession of the Titaness Themis. Python's breath came through a chasm and in its fumes held prophecies. A priestess at the temple would breathe in the fumes and speak the Oracle in the form of a riddle.
Apollo killed Python after he tried to block his way to the chasm, and he captured the Oracle. Pan had supposedly taught Apollo divination, so he was able to take over the task of guarding it. The outcome showed that the Olympian gods of light overpowered the gods of darkness. From that moment on, Apollo became worshipped as an esteemed god of many categories.
