My Legend

Maslama al-Majriti (Arabic أبو القاسم مسلمة بن أحمد المجريطي) (b. Madrid – d. 1008 or 1007 CE), was an Arab Muslim astronomer, chemist, mathematician and scholar in Islamic Spain. He took part in the translation of Ptolemy's Planispherium, improved existing translations of the Almagest, introduced and improved the astronomical tables of al-Khwarizmi, aided historians by working out tables to convert Persian dates to Hijri years, and introduced the techniques of surveying and triangulation.

The authorship of part of the Encyclopedia of the Brethren of Sincerity has also been attributed to him, but this is unlikely. The authorship of the famous Picatrix is also attributed to him.
