 Horace's poems continued to be school texts into late antiquity.Works attributed to Helenius Acro and Pomponius Porphyrio are the remnants of a much larger body of Horatian scholarship.Porphyrio arranged the poems in non-chronological order, beginning with the "Odes", because of their general popularity and their appeal to scholars (the "Odes" were to retain this privileged position in the medieval manuscript tradition and thus in modern editions also).
