Abu Ali al-Hassan al-Marrakushi (Arabic : الحسن المراكشي; late 13th century) was a Maghreb astronomer and mathematician from the Kingdom of Morocco . He was especially important in the field of trigonometry and practical astronomy. He wrote Jāmiʿ al-mabādiʾ wa’l-ghāyāt fī ʿilm al-mīqāt (Collection of the Principles and Objectives in the Science of Timekeeping), a treatise on spherical astronomy and astronomical instruments. ^[1] The first part was translated into French by the orientalist and astronomer Jean Jacques Emmanuel Sédillot  [ fr ] during the early 19th century, and published after Sédillot's death. ^{[2] [ page needed ]}

The treatise, which was written in Cairo between 1276 and 1282, is regarded as the most complete source to have survived about medieval Islamic astronomical instruments. ^{[3] [ page needed ] [4]}
