The transfer of mathematical knowledge to the Christian West took place mainly through the regions of contact between the Islamic world and Europe, such as the part of the Iberian Peninsula under Muslim rule (known as
al-Andalus,
see the article), Sicily and southern Italy. These territories, then ruled in the name of Islam or maintaining close relations with the Islamic world, became cultural bridges between the two civilizations. It was in this context that many European scholars traveled to the great cities of Muslim Spain. Undoubtedly, one of the most emblematic centers of this movement was Toledo, reconquered by the Christians in 1085. The city quickly became a crossroads where Christian, Jewish and Muslim scholars collaborated on the translation of scientific and philosophical texts. Cordoba and Seville also played an important role.
