De coloribvs libellvs
A 1548 Latin treatise on colour by Simone Porzio, printed in Florence by Laurentius Torrentinus and drawing on Aristotle's work of the same subject. The pictures are a calligraphic bookplate for Theodore Besterman, with flourished lettering inside a fine ruled border, and a woodcut historiated initial C showing a mounted knight with a lance attacking a dragon-like creature. A designer could take the flourished script and the framed woodcut initial as models for ornamental lettering and decorative capitals.
