Opera mathematica Ioannis Schoneri Carolostadii in unum uolumen congesta, et publicæ utilitati studiosorum omnium, ac celebri famæ Norici nominis dicata.
A 1561 Latin mathematical and astronomical compendium by Johann Schöner, edited by his son Andreas Schöner, with a preface by Philipp Melanchthon, printed in Nuremberg by Johann Montanus and Ulrich Neuber for students of mathematics. Its pictures are woodcut astrological horoscope charts and printed astronomical dial diagrams, showing how circular figures, zodiac signs and planetary positions were laid out on the page, which a designer could borrow for geometric or celestial ornament.
