Thus, like Hathor, she sometimes took the form of Imentet, the goddess of the west, who welcomed the deceased soul into the afterlife as her child. But for much of Egyptian history, male deities such as Osiris were believed to provide the regenerative powers, including sexual potency, that were crucial for rebirth. Isis was thought to merely assist by stimulating this power. Feminine divine powers became more important in afterlife beliefs in the late New Kingdom.

Isis continues to assist her son when he challenges Set to claim the kingship that Set has usurped, although mother and son are sometimes portrayed in conflict, as when
