The centre and home of the worship of Osiris in Egypt under the early
dynasties was Abydos, where the head of the god was said to be buried.
It spread north and south in the course of time, and several large
cities claimed to possess one or other of the limbs of his body. The
various episodes in the life of the god were made the subject of solemn
representations in the temple, and little by little the performance of
the obligatory and non-obligatory services in connection with them
occupied, in certain temples, the greater part of the time of the
priests. The original ideas concerning the god were forgotten and new
ones grew up; from being the _example_ of a man who had risen from the
dead and had attained unto life everlasting, he became the _cause_ of
the resurrection of the dead; and the power to bestow eternal life upon
mortals was transferred from the gods to him. The alleged dismemberment
of Osiris was forgotten in the fact that he dwelt in a perfect body in
the underworld, and that, whether dismembered or not, he had become
after his death the father of Horus by Isis. As early as the XIIth
dynasty, about B.C. 2500, the worship of this god had become almost
universal, and a thousand years later Osiris had become a sort of
national god. The attributes of the great cosmic gods were ascribed to
him, and he appeared to man not only as the god and judge of the dead,
but also as the creator of the world and of all things in it. He who was
the son of R[=a] became the equal of his father, and he took his place
side by side with him in heaven.

We have an interesting proof of the identification of Osiris with R[=a]
in Chapter XVII. of the Book of the Dead. It will be remembered that
this Chapter consists of a series of what might almost be called
articles of faith, each of which is followed by one or more explanations
which represent one or more quite different opinions; the Chapter also
