Osiris bildade tillsammans med sin hustru och son en central gudomlig triad i den egyptiska gudaskaran. Ursprungligen var Osiris en fruktbarhets- och sädesgud men liksom många andra egyptiska gudar ändrades hans funktion med tiden. Osiris personifierade pånyttfödelsen och berättelsen om honom utgjorde en förebild för de viktiga egyptiska begravningsriterna.[1][2][3][4]

^"The willy Seth claimed the kingship but was challenged by Osiris's son Horus... the kings regarded themselves as Horus, the rightful heir of Osiris... It shows the posthumous conception of Horus as the deceased Osiris impregnates Isis.. as well as the Abydos triad (Osiris, Isis and Horus)... it neatly identifies the king with Horus and substantiates his claim to be the son and heir of Osiris. When the king died he was said to fly off on his falcon wings to join the sun god or to take his place among the stars. In other texts the king became Osiris while his son became the next living Horus." (Oakes 2006, sid. 150, 151 "The Myth of Kingship").
^"Hathor. ...As the living king was regarded as Horus, his mother was often held to be Isis. However, in the triads that decorated Menkaure's valley temple, Hathor, whose name means 'House of Horus', plays that role. ...'Are you Horus, the son of Isis? Are you the god, the eldest one, the son of Hathor." (Oakes 2006, sid. 61 "The Pyramid of Menkaure".)
