Thomas Aquinas (1224/25–1274) wrote commentaries on the four Gospels by stringing together quotations from the works of Greek and Latin Church Fathers and of later Church writers. Thus a catena (chain) was created, the best-known of all catenae. In the 14th century it was translated into German. Two of the universally treasured magnificent manuscripts with the commentaries on Mark and Luke were considered lost in the last year of the Second World War, but in 1982 they were discovered in Toru?. The present volume contains the edition of the Catena aurea super Lucam, the commentary on Luke.
