The Temple of Amun in Siwa was the primary residence of the exalted Oracle of Amun, who guided the affairs of the village, and a significant religious site. It was built directly above an Isu vault which was incorporated into the temple as an underground chamber.
In 49 BCE, Pharaoh Ptolemy XIII appointed Medunamun, a member of the Order of the Ancients, as Oracle of Amun in a bid to consolidate his control over the remote, dissident town. A year later, the Medjay Bayek of Siwa, freed a group of farmers from cages in the temple grounds, including Teremun, who had died from his wounds. He later carried his body out of the temple to his farm.
