Egypt
, Osiris was regarded as the chief god of the underworld but he was also depicted as a man holding the crook and the flail remained and Abydos was the center of his worship .
Osiris was worshiped in several temples and his statue appears in the drawings on the walls of Upper Egypt temples such as the temples of
Dendera
and Philae . He was usually depicted as a man wearing a beard , catching a crook and a flail in his hand and wearing the Mummy's white dress , and with a white crown of Lower Egypt and some times a white crown and two plumes over his head . Most of the scenes that depict Osiris present him topping the throne of
Maat
