In this work Peuerbach had elaborated a new theory of the planets, their spheres and movements, and had treated the most difficult points with unusual learning and distinctness. For nearly a hundred years this work continued to be the principal authority on astro- nomical science, and was used in all the schools of Europe as a preparation for higher mathematics. Another work of Peuerbach's on the eclipses of the sun and moon was also first brought out by Eegiomontanus, and was of a like epoch-making character. After the death of Peuerbach in 1461, at the age of thirty-eight, Eegiomontanus, at the invitation of Cardinal Bessarion, went to Italy.
