De urinis libri VII. Accedunt huic editione aliorum medicorum dissertationes de urinis. Quorum nomina versa pagina indicat
A Latin medical treatise on urine examination by the 13th-14th century Byzantine physician Joannes Actuarius, printed at Utrecht in 1670 with later commentaries by other physicians. The picture is a decorated initial C with scrolling acanthus-style foliage and a small floral blossom, beside a few lines of Latin text in roman type. A designer could take from it the dense, ornamental capital letter that anchors a text block and sets a scholarly, early-modern printed tone.
