+Isis+ (_Aset_ or _Isit_) became attached at a very early time to the Osiris worship; and appears in later myths as the sister and wife of Osiris. But she always remained on a very different plane to Osiris. Her worship and priesthood were far more popular than those of Osiris, persons were named after her much more often than after Osiris, and she appears far more usually in the activities of life. Her union in the Osiris myth by no moans blotted out her independent position and importance as a deity, though it gave her {44} a far more widespread devotion. The union of Horus with the myth, and the establishment of Isis as the mother goddess, was the main mode of her importance in later times. Isis as the nursing mother is seldom shown until the twenty-sixth dynasty; then the type continually became more popular, until it outgrew all other religions of the country. In the Roman times the mother Isis not only received the devotion of all Egypt, but her worship spread rapidly abroad, like that of Mithra. It became the popular devotion of Italy; and, after a change of name due to the growth of Christianity, she has continued to receive the adoration of a large part of Europe down to the present day as the Madonna. +Nephthys+ (_Neb-hat_) was a shadowy double of Isis; reputedly her sister, and always associated with her, she seems to have no other function. Her name, 'mistress of the palace,' suggests that she was the consort of Osiris at the first, as a necessary but passive complement in the system of his kingdom. When the active Isis worship entered into the renovation of Osiris, Nebhat remained of nominal importance, but practically ignored.
