The gateway of king Nectanebo II (350 - 341 BC). This is the entrance to the temple of Isis. Isis embodied the role of a nourishing goddess and wife of Osiris, she was the object of a cult long after the introduction of Christianity.
It was believed that Philea was one of those sacred places where a part of the mutilated body of Osiris was buried. The Island was the venue for one of the annual Osiris passion plays which brought vast crowds of worshipers.
