Answer
Osiris-Antinous cult was a Roman religion that was devoted to the worship of the deified Antinous, a youth who was a lover of Roman emperor Hadrian. The cult was created by Hadrian himself, who believed that Antinous was the incarnation of the Egyptian god Osiris. The cult became increasingly popular after Antinous' death in 130 AD, and there are many surviving examples of temples, shrines, and statues dedicated to Antinous.
