Summa omnium haeresum et catalogus schismaticorum, haereticorum, et idolatrarum
A 1581 Latin catalogue of heresies and schismatics compiled by Sebastiano Medici and printed at the Sermartelli press, aimed at clerical and scholarly readers. Its pictures are woodcut decorative initial letters: a Q framed by a scrolled border with a shell-like figure inside, and an ornate P built from foliate strapwork and acanthus-style scrolls, useful to designers seeking historic letterform frames and border ornament.
