Speculum Romanae Magnificentiae: St. Peter's
The Speculum Romanae Magnificentiae is a collection of engravings of Rome and Roman antiquities, the core of which consists of prints published by Antonio Lafreri and gathered under a title page he printed in the mid-1570's. Copies of the Speculum vary greatly in the number of prints, and individual prints were reissued and changed over time.
In 1540 Antonio Lafreri, a native of Besançon transplanted to Rome, began publishing maps and other printed images that depicted major monuments and antiquities in Rome. These images were produced to appeal to the taste for classical antiquity that fueled the Renaissance. After Lafreri published a title page in the mid-1570s, collections of these prints came to be known as the Speculum Romanae Magnificentiae, the "Mirror of Roman Magnificence." Tourists and other collectors who bought prints from Lafreri made their own selections and had them individually bound. Over time, Lafreri's title page served as starting point for large and eclectic compilations, expanded and rearranged by generations of collectors.
