About “Tabulæ Prutenicæ”
The Prutenic Tables were an ephemeris published by the astronomer Erasmus Reinhold in 1551. They were also known as the Prussian Tables, named after Albert I, Duke of Prussia, who supported and funded their publication. Reinhold based his calculations on Nicolaus Copernicus' De revolutionibus orbium coelestium, published in 1543, which presented the heliocentric model of the solar system. Reinhold used the position of Saturn on 17 May 1490, the day the Duke was born, as a reference point in his tables. He aimed to replace the older Alfonsine Tables and included additional tables to help almanac compilers transition from the old system to the new one. (Summary adapted from Wikipedia, CC BY-SA 4.0.)
