John Ruskin,
The Stones of Venice, Volume 1…
“ But the Venetian habitually incrusted his work with nacre; he built his houses, even the meanest, as if he had been a shell-fish,—roughly inside, 272 mother-of-pearl on the surface: he was content, perforce, to gather the clay of the Brenta banks, and bake it into brick for his substance of wall; but he overlaid it with the wealth of ocean, with the most precious foreign marbles. You might fancy early Venice one wilderness of brick, which a petrifying sea had beaten upon till it coated it with marble: at first a dark city—washed white by the sea foam. ”
