Abu as-Salt

Abū aṣ-Ṣalt Umayya ibn ʿAbd al-ʿAzīz ibn Abī aṣ-Ṣalt ad-Dānī al-Andalusī, known in Latin as Albuzale, was an Andalusian-Arab polymath who wrote about pharmacology, geometry, Aristotelian physics, and astronomy. His works on astronomical instruments were read both in the Islamic world and Europe. He also occasionally traveled to Palermo and worked in the court of Roger I of Sicily as a visiting physician. He became well known in Europe through translations of his works made in the Iberian Peninsula and in southern France. He is also credited with introducing Andalusi music to Tunis, which later led to the development of the Tunisian ma'luf.
