Figure C19 TRAVERTINE
Toward the south, our vision blocked by steam.
A whiff of sulphur and the sound of drops;
A gust of wind unveils, and, like a dream,
Appears a mighty terrace: from the tops
Of each stepp’d level, trickling water plops
Down to the next, and the droplets bear
Dissolvéd lime, insensibly which stops
To build, atom by atom, a rocky stair
Flowing, liquid, stony, lovely beyond compare.
