The Old Toledo School of Translators was decisive for the culture of the Middle Ages. The group of translators and scholars is now known under this name, which met in Toledo after its conquest by Alfonso VI and the arrival of the Order of Cluny. Christians, Muslims and Jews lived together in the city, so that Latin, Arabic and Hebrew were all common languages; moreover, as is logical were the different forms of romance, both from the Mozarabs who lived in Toledo and the Castilian conquerors.
The School had basically two periods. The first, marked by Archbishop Raimundo in the 12th century, and the second by King Alfonso X in the 13th century. An extraordinary number of works were translated into Arabic and, to a lesser extent, into Hebrew, containing much of the scientific and philosophical legacy of old classical Greek, Indian and Arabic.
