Percival Leigh, Manners and customs of ye Englyshe… (1849)
“ Wonderfull how still all the House was while Sontag was a singing of "Deh! vieni non tardar," and the Bravas and Clapping of Hands when me had ended; and what did as much as any Thing please me in her Singing was to hear how she did stick to the Text, and not, like a vulgar silly Prima Donna, disfigure noble Musique by ridiculous Flourishes. The House extraordinary full, though the Season over; and to compare the fine Foreheads and Faces of an Audience come to hear good Musique with the insignificant Looks of mere common Opera-Goers! Methinks I could never hear Figaro often enough ”
