Before dealing with the special varieties of the Egyptians' belief in gods, it is best to try to avoid a misunderstanding of their whole conception of the supernatural. The term god has come to tacitly imply to our minds such a highly specialised group of attributes, that we can hardly throw our ideas back into the more remote conceptions to which we also attach the same name. It is unfortunate that every other word for supernatural intelligences has become debased, so that we cannot well speak of demons, devils, ghosts, or fairies without implying a noxious or a trifling meaning, quite unsuited to the ancient deities that were so beneficent and powerful. If then we use the word god for such conceptions, it must always be with the reservation that the word has now a very different meaning from what it had to ancient minds.
To the Egyptian the gods might be mortal; even Ra, the sun-god, is said to have grown old and feeble, Osiris was slain, and Orion, the great hunter of the heavens, killed and ate the gods. The mortality of gods has been dwelt on by Dr. Frazer (Golden Bough), and the many instances of tombs of gods, and of the slaying of the deified man who was worshipped, all show that immortality was not a divine attribute. Nor was there any doubt that they might suffer while alive; one myth tells how Ra, as he walked on earth, was bitten by a magic serpent and suffered torments. The gods were also supposed to share in a life like that of man, not only in Egypt but in most ancient lands. Offerings of food and drink were constantly supplied to them, in Egypt laid upon the altars, in other lands burnt for a sweet savour.
