This is a 1492 Venice printing of the collected works of Boethius, the Roman philosopher, issued by the Gregori printers and held in the Boston Public Library, aimed at scholars of arithmetic and music theory. The four pictures are plain geometric diagrams in woodcut-style line work: a triangle with a horizontal bar, a lozenge split into labelled sections with Roman numerals, a rectangle crossed by a diagonal, and a triangle with crossing lines and letter labels, offering a designer clean, schematic linework and labelled diagram layouts.
