Arab invaders brought a new culture rich in medical and scientific knowledge.
The evolution of Latin into the Spanish language occurred simultaneously with the invasion of Spain by the Moors in 718 A.D. While the use of Latin expanded over the country, the Arab conquerors introduced a new culture rich in medical and scientific knowledge. During the 8th and 9th centuries, the Moors used their Baghdad House of Wisdom to translate this abundance of new intelligence into Latin. The Arabs also contributed vast works of literature from India and Persia which were translated through a variety of intermediary languages. These offerings included the Arabian Nights, the Koran and the Bible.
Two hundred years after the Moorish onslaught, Archbishop Raimundus (also known as Raymond Lull) built his School of Translators in Toledo. His goal was to translate the treasure trove of scientific and technological works gifted to Spain by the Arab invaders.
