Gemma Frisius, a physician and mathematician, wrote this 1545 Latin treatise on the astronomical and geometrical radius, printed at Antwerp and Louvain for a learned readership of scholars and instrument makers. Its pages show large decorated initial letters in woodcut, set beside dense black-letter text and diagram-free columns, with ornamental scrollwork and foliage filling each capital.
