text_A: Averroes's main influence on the Christian west was through his extensive commentaries on Aristotle. After the fall of the Western Roman Empire, western Europe fell into a cultural decline. However, the intellectual legacy of the Classical Greek scholars, including Aristotle, remained strong. Averroes's commentaries, which were translated into Latin and entered western Europe in the thirteenth century, provided an expert account of Aristotle's legacy and made them available again. The influence of his commentaries led to Averroes being referred to simply as "The Commentator" rather than by name in Latin Christian writings. He has been sometimes described as the "father of free thought and unbelief" and "father of rationalism".
text_B: In the twelfth century, was Plato well known in western Europe?
YES.
