La perfettione del cavallo, libri tre, di Francesco Liberati Romano
A 1669 Italian treatise on horsemanship by Francesco Liberati of Rome, aimed at horsemen and riding masters, with its pictures showing heraldic-style shield and crown devices. The four woodcut-style pictures are simple outlined emblems: a crown over a rope-edged lattice, a shield with a cross and a letter I, a crown over a diamond framing the letter O, and a shield with a cross and a letter T. A designer could draw on their bold, rope-textured outlines and monogram-in-shield structure for crest or badge work.
