Raymond of Marseilles

from Wikipedia, the free encyclopedia

Raymond von Marseille (* before 1120; † in the 12th century) was a French astronomer and astrologer .

Little is known about him - his name appears on one of the manuscripts of his works (Liber cursuum planetarum), so that the name Raymond von Marseille was first ascribed to the author in 1924. He worked in Marseille in 1141 and before.

Three works by Raymond von Marseille have survived:

  • Treatise on the astrolabe ( Vite presentis indutias silentio .. ), preserved in a manuscript in Paris. It covers both the construction and the use of the astrolabe. It is one of the first Latin texts that convey an exact knowledge of the instrument in the West - there were earlier Latin texts from the 10th and 11th centuries, but they were not as precise. There are also star tables in the work and he uses Az-Zarqali as a source but also, for example, Hermann von Reichenau's book on the astrolabe.
  • Liber cursuum planetarum , astronomical tables with an introduction in which the planetary movement is also discussed. The work is preserved in three manuscripts (Paris National Library, Fitzwilliam Museum Cambridge, Corpus Christi College Oxford) and was first analyzed by Pierre Duhem . Raymond of Marseille used the Toledaner tables and the work of az-Zarqali, adapting the tables to the geographical latitude of Marseille. The work was created in 1140 before the translation of the Toledaner Tafeln by Gerhard von Cremona and before his Latin translation of the Almagest (1175) and thus shows the earliest influences of Greek astronomy mediated by the Arabs in the Latin West.
  • Liber judiciorum , on astrology, survived in about 10 manuscripts. It was long considered missing, but was then identified with A philosophis astronomiam sic difinitam , a work previously attributed to Johannes Hispalensis .

The attribution of the Liber Judiciorum and the treatise on the astrolabe is based on references in the Liber cursuum planetarum.

In the 14th century, Nikolaus von Kues ascribes a translation of a work on alchemy (Theorica occultorum) to a Ramundus Marsiliensis, who is possibly identical with Raymond of Marseille.
