I went with some ladies to see a nun at St. Domenico's convent. […] While admiring the high altar, I heard the nuns, unseen, begin their vespers, which they chanted divinely; the distance, the seclusion, the quality of those noble ladies, made it more interesting. In the midst of rich architecture, twelve large jasper columns, rilievi in bronze, paintings of Luca Giordano, and a church hung with embroidered satin for the approaching festival of the saint,—I had no eyes till the music ceased.
