Specvlationi di mvsica, dedicate all'eminentiss ..
A 1670 music-theory treatise by Pietro Mengoli, printed in Bologna by the heirs of Benacci and dedicated to an eminent patron. Its four pictures are decorative woodcut initials, a cut-letter I, a C, an L and an N, set in foliage, flowers and scrolling vines. A designer could take from them the letterforms and the dense black-and-white ornament of 17th-century Italian printing for monograms, drop caps and borders.
