It is not enough for poems to be beautiful; they must be affecting, and must lead the heart of the hearer as they will. - Horace

For why do you hasten to remove things that hurt your eyes, but if anything gnaws your mind, defer the time of curing it from year to year?

Once a word has been allowed to escape, it cannot be recalled.

Come, Mercury, by whose minstrel spell Amphion raised the Theban stones,
Come, with thy seven sweet strings, my shell,
Thy "diverse tones," Nor vocal once nor pleasant, now To rich man's board and temple dear: Put forth thy power, till Lyde bow Her stubborn ear.
