Antonio all' Esquilino, on the left side of S. Maria Maggiore. [20] These incrustations, and the basilica to which they belong, have been illustrated by Ciampini: _Vetera monumenta_, vol. i. plates xxii.-xxiv.--D'Agincourt: _Histoire de l'art, Peinture_, pl. xiii. 3.--Minutoli: _Ueber die Anfertigung und die Nutzanwendung der färbigen Gläser bei den Alten_, pl. iv.--De Rossi: _La basilica di Giunio Basso_, in the _Bullettino di archeologia cristiana_, 1871, p. 46.
