Greek philosopher Aspasius would later be joined by medieval Christian scholars contributing to what massof literature?
Aspasius Aspasius ( ; Greek: Ἀσπάσιος ; c. 80 – c. 150 AD) was a Peripatetic philosopher. Boethius, who frequently refers to his works, says that Aspasius wrote commentaries on most of the works of Aristotle. The following commentaries are expressly mentioned: on "De Interpretatione", the "Physica", "Metaphysica", "Categoriae", and the "Nicomachean Ethics". A portion of the commentary on the "Nicomachean Ethics" (books 1, 2, 4, 7, and 8) is extant. The Greek text of this commentary has been published as "Commentaria in Aristotelem Graeca" (CAG) vol. 19.1, and David Konstan has published an English translation. It is notable as the earliest extant commentary on any of Aristotle's works. From Porphyry, who also states that Aspasius wrote commentaries on Plato, we learn that his commentaries on Aristotle were used in the school of Plotinus.
Catharism Catharism ( ; from the Greek: καθαροί , "katharoi", "the pure [ones]") was a Christian dualist or Gnostic revival movement that thrived in some areas of Southern Europe, particularly northern Italy and southern France, between the 12th and 14th centuries. The followers were known as Cathars and are now mainly remembered for a prolonged period of persecution by the Catholic Church which did not recognise their belief as truly Christian. It appeared in Europe in the Languedoc region of France in the 11th century and this is when the name first appears. The adherents were also sometimes known as Albigensians after the city Albi in southern France where the movement first took hold. The beliefs are believed to have been brought from Persia or the Byzantine Empire.
