Almagstum novum, written by Giovanni Battista Riccioli, was one of the earliest published books on astronomy. Riccioli gave names to craters and mountains on the moon, most of which are still in use today.
A competent astronomer and Jesuit priest, Riccioli published his massive New Almagest, a work that discussed the efforts of both Copernicus and Kepler but which sought to demonstrate that the earth was stationary. It was deemed a reference book and textbook for astronomers immediately upon its publication and is still the single most important reference work in the history of astronomy from 1550-1650. Riccoli, Giovanni Battista (1598-1671)
Originally planned in two volumes; only the first volume, in two parts appeared. Almagestum novum was acquired by Fondren Library as part of its celebration to mark its one millionth volume in 1979.
