"How are we to explain the rule that at a certain point of his reign every Pharaoh must undergo this ritual death followed by fictitious rebirth? Is it simply a renewal of the initiation into the Osirian mysteries? or does the festival present some more special features? The ill-defined part played by the royal children in these rites seems to me to indicate that the Sed festival represents other episodes which refer to the transmission of the regal office. At the dawn of civilization in Egypt the people were perhaps familiar with the alternative either of putting their king to death in his full vigour in order that his power should be transmitted intact to his successor, or of attempting to rejuvenate him and to 'renew his life.' The latter measure was an invention of the Pharaohs. How could it be carried out more effectively than by identifying themselves with Osiris, by applying to themselves the process of resurrection, the funeral rites by which Isis, according to the priests, had magically saved her husband from death? Perhaps the fictitious death of the king may be regarded as a mitigation of the primitive murder of the divine king, a transition from a barbarous reality to symbolism."(424)
(M129) Whether this interpretation of the Sed festival be accepted in all its details or not, one thing seems quite certain: on these solemn occasions the god Osiris was personated by the king of Egypt himself. That is the point with which we are here chiefly concerned.
(M130) Thus far we have discussed the character of Osiris as he is presented to us in the art and literature of Egypt and in the testimonies of Greek writers; and we have found that judged by these indications he was in the main a god of vegetation and of the dead. But we have still to ask, how did the conception of such a composite deity originate? Did it arise simply through observation of the great annual fluctuations of the seasons and a desire to explain them? Was it a result of brooding over the mystery of external nature? Was it the attempt of a rude philosophy to lift the veil and explore the hidden springs that set the vast machine in motion? That man at a very early stage of his long history meditated on these things and evolved certain crude theories which partially satisfied his craving after knowledge is certain; from such meditations of Babylonian and Phrygian sages appear to have sprung the pathetic figures of Adonis and Attis; and from such meditations of Egyptian sages may have sprung the tragic figure of Osiris.
