Horace composed in traditional metres borrowed from Archaic Greece, employing hexameters in his "Satires" and "Epistles", and iambs in his "Epodes", all of which were relatively easy to adapt into Latin forms. His "Odes" featured more complex measures, including alcaics and sapphics, which were sometimes a difficult fit for Latin structure and syntax. Despite these traditional metres, he presented himself as a partisan in the development of a new and sophisticated style. He was influenced in particular by Hellenistic aesthetics of brevity, elegance and polish, as modelled in the work of Callimachus.
