Muratori's 1778 Antiquitates Italicae Medii Aevi is a Latin scholarly treatise on medieval Italian customs, religion, government and laws, edited by Lodovico Antonio Muratori and held by Heidelberg University Library. The pictures are small printed devices: monograms built from crossed and interlocking capital letters, and a circular papal seal reading LEGIMUS with SCS PETRUS PAULUS and URBANUS PP. II, showing how letterforms were fitted into symmetrical geometric frames.
