In one of his discourses about beauty [bk 22, ch 24 of "The City of God"], he says:
Of course, some parts of the human body appear to have no other purpose than to add beauty, as the mamillae on a man's chest or the beard on his face. Certainly if the beard were meant for protection rather than for beauty, it would have served a better purpose for the weaker sex, whose face remains uncovered... I think, that in the creation of the human body, God put form before function.
All of this is Augustine articulating the intricate beauties that we get to partake in. He also talks about architecture, agriculture, navigation, language, rhythm, poise, symmetry, etc, etc. He closes this chapter by saying:
Remember, all these favors taken together are but the fragmentary solace allowed us in a life condemned to misery. What, then, must be the consolations of the blessed, seeing that men on earth enjoy so much of so many and of such marvelous blessings? What good will God not give to those predestined to eternal life, if He gives so much to those who are doomed to death?
