Statius paid homage to Horace by composing one poem in Sapphic and one in Alcaic meter (the verse forms most often associated with "Odes"), which he included in his collection of occasional poems, "Silvae". Ancient scholars wrote commentaries on the lyric meters of the "Odes", including the scholarly poet Caesius Bassus. By a process called "derivatio", he varied established meters through the addition or omission of syllables, a technique borrowed by Seneca the Younger when adapting Horatian meters to the stage.
