“ Procopius’s theological writings consist of commentaries on the Octateuch, the books of Kings and Chronicles, Isaiah, the Proverbs, the Song of Songs and Ecclesiastes. They are amongst the earliest examples of the “catenic” (catena, chain) form of commentary, consisting of a series of extracts from the fathers, arranged, with independent additions, to elucidate the portions of Scripture concerned. Photius (cod. 206) , while blaming the diffuseness of these commentaries, praises the writer’s learning and style, which, however, he considers too ornate for the purpose. ”
