Sur les traces du de motibus / iudiciis planetarum attribué à Ptolémée

摘要

A short astrological treatise about the properties of the planets in the zodiac, called De motibus / iudiciis planetarum and attributed to Ptolemy (inc. Sub Saturno sunt hec signa Capricornus et Aquarius et sunt eius domus), appears from the thirteenth century onwards in two distinct traditions: in the encyclopedias of Bartholomew the Englishman and Arnold of Saxony, both written around 1230-1240, and in astronomical miscellanies copied in the fifteenth century either in or around Basel and in Northern Italy. These fifteenth-century manuscripts fall into two distinct groups of astronomical texts: the first is copied together with the De signis of Michael Scot, the second together with a part of the third book of Hyginus' De astronomia. The present article aims to describe the characteristics of the distinct textual filiations of De m. / iud. pl. and gives the first critical edition of the text.
