Stendhal, Life of Henri Brulard, (trans. Catherine Alison Phillips):

And here, as I could not tell what to say, I began again, without thinking, to admire the sublime aspect of the ruins of Rome and its modern grandeur: opposite me the Coliseum; and, beneath my feet, the Farnese Palace, with its beautiful arcaded loggia full of modern works; the Corsini Palace, too, beneath my feet.

Farnese Palace. Corsini Palace. Wikipedia:

is the name given to an architectural feature, originally of Italian design. They are often a gallery or corridor at ground level, sometimes higher, on the facade of a building and open to the air on one side, where it is supported by columns or pierced openings in the wall.
