Note 202 — Chapter XIV
Reading edition
Sixtus of Sienna and Trithemius both declare that St. Thomas explained all the works of Aristotle, and that he was the first Latin Doctor who did so, but the Commentaries that are preserved treat only of fifty two books. This purgation of the pagan philosophy is alluded to in the Matins hymn for his office, as forming one of his chief glories:
Plusquam doctores cæteri Purgans dogma Gentilium.
