Libri tres de institvtione harmonica
A 1516 music theory treatise in three books by Pietro Aaron, edited from Antonio Flaminio's Latin translation and printed in Bologna by bookseller Benedetto Faelli for scholars and musicians. The title page sits in a dense woodcut border of flowers, leaves and fruit around a centred black-letter block, and the second picture is a bold printer's or owner's mark of a cross over a circle with a triangle and a letter B, a strong graphic emblem a designer could adapt.
