With the loss of the study of ancient Greek in the early [[medieval]] Latin West, Aristotle was practically unknown there from {{Circa|CE 600}} to {{Circa|1100}} except through the Latin translation of the ''Organon'' made by [[Boethius]]. In the twelfth and thirteenth centuries, interest in Aristotle revived and Latin Christians had translations made, both from Arabic translations, such as those by [[Gerard of Cremona]],{{sfn| Hasse | 2014}} and from the original Greek, such as those by [[James of Venice]] and [[William of Moerbeke]].

After the [[Scholasticism|Scholastic]] Thomas Aquinas wrote his ''[[Summa Theologica]]'', working from Moerbeke's translations and calling Aristotle "The Philosopher",{{sfn|Aquinas|2013}} the demand for Aristotle's writings grew, and the [[Greek language|Greek]] manuscripts returned to the West, stimulating a revival of Aristotelianism in Europe that continued into the [[Renaissance]].{{sfn| Kuhn | 2018}} These thinkers blended Aristotelian philosophy with Christianity, bringing the thought of Ancient Greece into the Middle Ages. Scholars such as Boethius, [[Peter Abelard]], and [[John Buridan]] worked on Aristotelian logic.{{sfn| Lagerlund}}

According to scholar Roger Theodore Lafferty, [[Dante]] built up the philosophy of the ''[[Divine Comedy|Comedy]]'' with the works of Aristotle as a foundation, just as the scholastics used Aristotle as the basis for their thinking. Dante knew Aristotle directly from Latin translations of his works and indirectly through quotations in the works of [[Albert Magnus]].<ref>Lafferty, Roger.
