Serapis

i.e. Osiris-Apis, or Ausar Hapi. This god is a combination of the Apis with Osiris, and was introduced into Egypt by the Ptolemies. He is accounted to be the second son of Ptah, and is represented with a bull's head surmounted by a disk and uraeus. His worship extended all over the kingdom, and was very popular under the Roman domination.
