The Bayt al-Hikma, or House of Wisdom, was the library and scholarly centre of Abbasid Baghdad that reached its height under the caliph al-Ma'mun around 830, at the core of a vast state-backed translation movement. Over roughly two centuries, scholars systematically rendered Greek, Persian, Syriac and Sanskrit works of philosophy, mathematics, medicine, astronomy and engineering into Arabic, often improving and extending them. The effort preserved much classical learning that might otherwise have been lost and fused it with Indian and Persian science into a common body of knowledge. From Baghdad this corpus diffused across the Islamic world and, via Spain and Sicily, back into Latin Europe.
The translation movement assembled and advanced the scientific and mathematical knowledge later applied to surveying, engineering, hydraulics and astronomy across cities of three continents. By transmitting and enlarging the classical inheritance, it became a principal channel through which ancient learning reached medieval Europe.
