Plotinus,
Plotinos: Complete Works, v. 3
“ So long as she contemplates Intelligence, she surely enjoys a noble and magnificent spectacle, but she does not yet fully possess the object of her search. Such would be a human countenance, which, in spite of its beauty, is not attractive, for lack of the charm of grace. Beauty is, indeed, rather the splendor that enhalos proportion, than proportion itself; and it is properly this splendor which challenges love. Why indeed does beauty shine radiantly on the face of a living person, and yet leave hardly a trace after death, even when the complexion and features are not yet marred? ”
