 Reinhold knew about Copernicus and his heliocentric ideas prior to the publication of his "De revolutionibus", and made a favourable reference to him in his commentary on Purbach.However, Reinhold (like other astronomers before Kepler and Galileo) translated Copernicus' mathematical methods back into a geocentric system, rejecting heliocentric cosmology on physical and theological grounds.Duke Albert of Brandenburg Prussia supported Reinhold and financed the printing of Reinhold's "Prutenicae Tabulae" (1551, 1562, 1571 & 1585) or "Prussian Tables".
