Of course the obvious physiological functions of the eyes as means of communication between their possessor and the world around him; the powerful influence of the eyes for expressing feeling and emotion without speech; the analogy between the closing and opening of the eyes and the changes of day and night, are all hinted at in Egyptian literature.
But there were certain specific factors that seem to have helped to give definiteness to these general ideas of the physiology of the eyes. The tears, like all the body moisture, came to share the life-giving attributes of water in general. And when it is recalled that at funeral ceremonies emotion found natural expression in the shedding of tears, it is not unlikely that this came to be assimilated with all the other water-symbolism of the funerary ritual. The early literature of Egypt, in fact, refers to the part played by Isis and Nephthys in the reanimation of Osiris, when the tears they shed as mourners brought life back to the god. But the fertilizing tears of Isis were life-giving in the wider sense. They were said to cause the inundation which fertilized the soil of Egypt, meaning presumably that the "Eye of Re" sent the rain.
There is the further possibility that the beliefs associated with the cowry may have played some part, if not in originating, at any rate in emphasizing the conception of the fertilizing powers of the eye. I have already mentioned the outstanding features of the symbolism of the cowry. In many places in Africa and elsewhere the similarity of this shell to the half-closed eyelids led to its use as an artificial "eye" in mummies. The use of the same objects to symbolize the female reproductive organs and the eyes may have played some part in transferring to the latter the fertility of the former. The gods were born of the eyes of Ptah. Might not the confusion of the eye with the genitalia have given a meaning to this statement? There is evidence of this double symbolism of these shells. Cowry shells have also been employed, both in the Persian Gulf and the Pacific, to decorate the bows of boats, probably for the dual purpose of representing eyes and conferring vitality upon the vessel. These facts suggest that the belief in the fertilizing power of the eyes may to some extent be due to this cowry-association. Even if it be admitted that all the known cases of the use of cowries as eyes of mummies are relatively late, and that it is not known to have been employed for such a purpose in Egypt, the mere fact that the likeness to the eyelids so readily suggests itself may have linked together the attributes of the cowry and the eye even in Predynastic times, when cowries were placed with the dead in the grave.
Hathor's identification with the "Eye of Re" may possibly have been an expression of the same idea. But the rôle of the "Eye of Re" was due primarily to her association with the moon (vide infra, p. 56).
The apparently hopeless tangle of contradictions involved in these conceptions of Hathor will have to be unravelled. For "no eye is to be feared more than thine (Re's) when it attacketh in the form of Hathor" (Maspero, op. cit. p. 165). If it was the beneficent life-giving aspect of the eye which led to its identification with Hathor, in course of time, when the reason for this connexion was lost sight of, it became associated with the malevolent, death-dealing avatar of the goddess, and became the expression of the god's anger and hatred toward his enemies. It is not unlikely that such a confusion may have been responsible for giving concrete expression to the general psychological fact that the eyes are obviously among the chief means for expressing hatred for and intimidating and "brow-beating" one's fellows. [In my lecture on "The Birth of Aphrodite" I shall explain the explicit circumstances that gave rise to these contradictions.]
It is significant that, in addition to the widespread belief in the "evil eye"—which in itself embodies the same confusion, the expression of admiration that works evil—in a multitude of legends it is the eye that produces petrifaction. The "stony stare" causes death and the dead become transformed into statues, which, however, usually lack their original attribute of animation. These stories have been collected by Mr. E. S. Hartland in his "Legend of Perseus".
There is another possible link in the chain of associations between the eye and the idea of fertility. I have already referred to the development of the belief that incense, which plays so prominent a part in the ritual for conferring vitality upon the dead, is itself replete with animating properties. "Glaser has already shown the anti incense of the Egyptian Punt Reliefs to be an Arabian word, a-a-netc, 'tree-eyes' (Punt und die Südarabischen Reiche, p. 7), and to refer to the large lumps ... as distinguished from the small round drops, which are supposed to be tree-tears or the tree-blood."[94]

[92] In all probability the main factor that was responsible for conferring such definite life-giving powers upon the eye was the identification of the moon with the Great Mother. The moon was the Eye of Re, the sky-god.
