Serapeum

A serapeum is a temple or other religious institution dedicated to the syncretic Greco-Egyptian deity Serapis, who combined aspects of Osiris and Apis in a humanized form that was accepted by the Ptolemaic Greeks of Alexandria. There were several such religious centers, each of which was called a serapeion/serapeum (Ancient Greek: Σεραπεῖον) or poserapi (Ancient Greek: Ποσεραπι), coming from an Egyptian name for the temple of Osiris-Apis (Ancient Egyptian: pr-Wsỉr-Ḥp, lit. 'house of Osiris-Apis').^[1]
