Alternate Name

 John Danko of Saxony


John of Saxony was a pupil of and worked with  John of Lignères in Paris on a Latin version of the Alphonsine Tables. These tables for calculating planetary positions, prepared under the auspices of  Alfonso X, were originally in Spanish. John of Saxony wrote canons (explanations of the use) of the Latin version of the tables, which helped in spreading their use throughout Europe. In 1331 he also wrote a commentary on a work on astrology by  Qabīṣī, being careful to say nothing the church might object to. John calculated an Almanac for 1336–1380, based on the Alphonsine Tables as adapted for the Paris meridian.
