Knowledge transmission in medieval Spain

I enjoyed reading the article “Medieval weather prediction ” by Anne Lawrence-Mathers in the April 2021 issue of Physics Today (page 38). But one aspect of the author’s description of the transmission of knowledge from the Islamic world to Latin Europe caught my attention. She states, “Territorial conquests by northern European forces in the Iberian peninsula of al-Andalus made librarians, scholars, and translators available to the new Christian rulers.”

It is not easy to summarize in one sentence a complex historical process like the Iberian Reconquest, which lasted almost eight centuries. But during that Christian reconquest, periods of peace and tolerance between Christians, Muslims, and Jews were more common than periods of war and confrontation. In fact, some Leonese and Castilian kings’ tolerance of Muslims and Jews facilitated a cultural exchange that allowed the philosophical ¹ and scientific ² renaissance of the Iberian kingdoms and the entire Christian West.
