and to implant in it such power, that it can at once survey the high aerial expanse, and by the aid of a small pupil embrace the mountains, forests, hills, the ocean, yea, the heaven, by so small a thing! Tell me not then of tears and rheums, for these things are the fruit of thy sin; but consider its beauty, and visual power; and how it is that whilst it ranges over such an expanse of air, it experiences no weariness or distress! The feet indeed become tired and 415 weakened even after going but a small distance; but the eye, in traversing a space so lofty and so wide, is not sensible of any infirmity. For since this is the most necessary to us of all our members, He has not suffered it to be oppressed with fatigue; in order that the service it renders us might be free and unfettered. 7. But rather, I should say, what language is fully adequate to set forth the whole excel- lency of this member? And why do I speak of the pupil and the visual faculty? for if you were to investigate that which seems the meanest of all the members, I mean the eyelashes, you would behold even in these the manifold wisdom of God the Creator! For as it is with respect to the ears of corn; the beards, standing forth as a sort of spears, repel the birds, and do not suffer them to settle upon the fruits, and to break the stalk, which is too tender to bear them; so also is it with regard to the eyes. The hairs of the eyelids are ranged in front, and answer the purpose of beards and spears; keeping dust and light substances at a distance from the eyes, and any thing that might incommode the sight; and not permitting the eyelids to be annoyed. Another instance of wisdom, no less remarkable, is to be observed in eyebrows. Who can help being struck by their position? For they do not project to an immoderate degree, so as to obscure the sight; nor do they retire farther back than is fitting; but in the same manner as the eaves of a house, they stand out above, receiving the perspiration as it descends from the forehead, and not permitting it to annoy the eyes. For this purpose too there is a growth of hair upon them, which serves by its roughness to stay what descends from above, and affords the exact protection that is needed, and contributes also much ap- pearance of beauty to the eyes. Nor is this the only matter of wonder! There is another thing also which is equally so. How is it, I ask, that the hairs of the head increase, and are cut off; but those of the eyebrows, not so? For not even this has happened undesignedly, or by chance, but in order that they might not darken the sight too much by becoming very long; an inconvenience from which those suffer who have arrived at extreme old age. 8. And who could possibly trace out all the wisdom which is manifested by means of the brain! For, in the first place, He made it soft, since it serves as a fountain to all the senses. Next, in order that it might not suffer injury owing to its peculiar nature, He fortified it on every side with bones. Further; that it might not suffer from friction, by the hardness of the bones, He interposed a middle membrane: and not only a single one, but also a second; the former being spread out on the under side of the skull, but the latter enveloping the upper substance of the brain, and the first being the harder of the two. And this was done, both for the cause that has been mentioned, and in order that the brain might not be the first to 600 Homily XI
