Muratori's 1778 Antiquitates Italicae Medii Aevi is a Latin scholarly work on medieval Italian customs, religion, government and laws, edited by Lodovico Antonio Muratori and printed for antiquarian scholars. Its pictures are small woodcut-style monograms, seals and coin-like emblems, including a round papal seal reading Petrus Paulus Eugenius PP III, which a designer might take as models for compact monograms, roundel seals and interlocking initial letterforms.
