Planisphaerium Versatile

Planisphaerium Versatile, by Johann Baptist Inninger, is a comprehensive treatise on the celestial sphere and its representation through the use of a planisphere. Written in Latin, this work delves into the construction and application of the planisphere for solving over 200 astronomical problems related to both solar and lunar phenomena. The book begins with a detailed explanation of the parts and circles of the celestial sphere, providing a foundational understanding for the subsequent complex calculations and diagrams.

This book offers a valuable resource for understanding the astronomical knowledge and practices of the 17th century. It will be of interest to historians of science, astronomers, and anyone fascinated by the intersection of mathematics, astronomy, and instrument-making in the early modern period. The detailed problems and solutions presented provide a unique insight into the methods used to understand and predict celestial events during this era.
