A quote
Some individual makes these vices fashionable—some person who controls the eloquence of the day; the rest follow his lead and communicate the habit to each other. Thus when Sallust was in his glory, phrases were lopped off, words came to a close unexpectedly, and obscure conciseness was equivalent to elegance.
