Osiris
(Ausar)
Who is Osiris, The Egyptian God ?
The god of the dead, and the god of the resurrection into eternal life; ruler, protector, and judge of the deceased, and his prototype (where in English we use the euphemism "the deceased" or "the late", Egyptians referred to "the Osiris"). His cult originated in Abydos, where his actual tomb was said to be located.
Osiris was the first child of Nut and Geb, thus the brother of Set, Nephthys, and Isis, who was also his wife. By Isis he fathered Horus, and according to some stories, Nephthys assumed the form of Isis, seduced him thus, and from their union was born Anubis.
Osiris ruled the world of men in the beginning, after Ra had abandoned the world to rule the skies, but he was murdered by his brother Set. Through the magic of Isis, he was made to live again. Being the first person to die, he subsequently became lord of the dead. His death was avenged by his son Horus, who defeated Set and cast him out into the desert to the West of Egypt (the Sahara).
Prayers and spells were addressed to Osiris throughout Egyptian history, in hopes of securing his blessing and entering the afterlife which he ruled; but his popularity steadily increased through the Middle Kingdom. By Dynasty 18 he was probably the most widely worshipped god in Egypt. His popularity endured until the latest phases of Egyptian history; reliefs still exist of Roman emperors, conquerors of Egypt, dressed in the traditional garb of the Pharaohs, making offerings to him in the temples.
