astronomical tables in Europe and updated versions were regularly produced for three hundred years. Nicolaus Copernicus, known as the father of modern astronomy, bought a copy while at the University of Cracow, and cared about it enough to have it professionally bound with pieces of wood and leather. Alexander Bogdanov maintained that these tables formed the basis for Copernicus's development of a heliocentric understanding in astronomy. In 1551, the Prutenic Tables (or Prussian Tables) of Erasmus Reinhold's were published. These tables used the Copernican heliocentric model of the solar system. Copernicus's publication, De revolutionibus, was not easy to use and the Prutenic tables were intended to make the heliocentric model more usable by astrologers and astronomers. However, the Prutenic tables were not widely adopted outside German speaking countries and new ephemerides based on the Alfonsine tables continued to be published until the publication of Johannes Kepler's Rudolphine Tables in 1627.
