Apis (also known as Hapi or Hepi) was a sacred bull deity in ancient Egyptian religion. The name Apis is derived from the ancient Egyptian word Hapi (ḥꜣpj), which means "to be bullish" or "to be strong." In Hebrew, the name is translated as אפיס (Apis). The Greeks identified Apis with their own deity, Apis (Ἄπις), and the Romans referred to him as Apis or sometimes Serapis, a syncretic deity that combined aspects of Apis with Osiris. The Apis bull was considered a manifestation of the god Ptah, the creator god of Memphis, and was believed to embody the life force and fertility of the land. The cult of Apis was centered in Memphis, where the bull was selected based on specific physical characteristics, such as a white triangle on its forehead, and was housed in a special sanctuary. The Apis bull played a crucial role in religious ceremonies and was mummified and buried in elaborate ceremonies upon its death, with its successor chosen and installed in a grand procession.
