Constantini Caesaris selectarum praeceptionum de agricultura libri uiginti
A Latin treatise on agriculture printed at Lyon in 1541 by the Gryphius press, published for farmers and estate managers. Its pictures are small woodcut historiated initials, each a large capital H framing a figure of a child or putto among foliage, repeated from block to block across the pages. A designer could take from them the compact, decorative power of a single repeated ornamental letter set within a bordered square.
