 His "Satires" are relatively easy-going in their use of meter (relative to the tight lyric meters of the "Odes") but formal and highly controlled relative to the poems of Lucilius, whom Horace mocked for his sloppy standards ("Satires" 1.10.56–61)

The "Epistles" may be considered among Horace's most innovative works.There was nothing like it in Greek or Roman literature.Occasionally poems had had some resemblance to letters, including an elegiac poem from Solon to Mimnermus and some lyrical poems from Pindar to Hieron of Syracuse.
