Horrificans Zephyrus proclivas incitat undas,
Aurorâ exoriente, vagi sub lumina solis;
Quæ tarde primum clementi flamine pulsæ
Procedunt, leviterque sonant plangore cachinni:
Post, vento crescente, magis magis increbescunt,
Purpureâque procul nantes a luce refulgent.
"As in early morning when Zephyr's breath, ruffling the stilly sea, stirs it into slanting waves up against the glow of the travelling sun; and at first, while the impelling breeze is gentle, they move in slow procession, and the plash of their ripples is not loud; but then, as the breeze freshens, they crowd faster and faster on, and far out at sea, as they float, flash back the splendour of the crimsoning day in their front."
Or, again, in the epistle to Manlius—
Qualis in aerii pellucens vertice montis
Rivus muscoso prosilit e lapide.
