At the beginning of Greek literature stand the two monumental works of Homer: the Iliad and the Odyssey. Though dates of composition vary, these works were fixed around 800 BC or after. In the classical period many of the genres of western literature became more prominent. Lyrical poetry, odes, pastorals, elegies, epigrams; dramatic presentations of comedy and tragedy; historiography, rhetorical treatises, philosophical dialectics, and philosophical treatises all arose in this period. The two major lyrical poets were Sappho and Pindar. The Classical era also saw the dawn of drama.
