AbstractGiovanni Bianchini’s fifteenth-century Tabulae primi mobilis is a collection of 50 pages of canons and 100 pages of tables of spherical astronomy and mathematical astrology, beginning with a treatment of the conversion of stellar coordinates from ecliptic to equatorial. His new method corrects a long-standing error made by a number of his antecedents, and with his tables the computations are much more efficient than in Ptolemy’s Almagest. The completely novel structure of Bianchini’s… Expand
Before the end of an error: Giovanni Bianchini’s original flawed treatise on the conversion of stellar coordinates
This article compares its canons and tables to Bianchini’s later work, noting the places where the contents overlap, and analyzes his mathematical methods and the unique tables he constructed for converting stellar coordinates, including the earliest known European arc sine table. Expand
