Perhaps the most leeringly blood-congealing legends are those which relate to certain perverse products of decadent priestcraft—composite mummies made by the artificial union of human trunks and limbs with the heads of animals in imitation of the elder gods. At all stages of history the sacred animals were mummified, so that consecrated bulls, cats, ibises, crocodiles, and the like might return some day to greater glory. But only in the decadence did they mix the human and animal in the same mummy—only in the decadence, when they did not understand the rights and prerogatives of the ka and the soul. What happened to those composite mummies is not told of—at least publicly—and it is certain that no Egyptologist ever found one. The whispers of Arabs are very wild, and cannot be relied upon. They even hint that old Khephren—he of the Sphinx, the Second Pyramid, and the yawning gateway temple—lives far underground wedded to the ghoul-queen Nitocris and ruling over the mummies that are neither of man nor of beast.
