Poetry (from the Greek word poiesis, "making") is a form of literary art that uses aesthetic and often rhythmic qualities of language to evoke meanings in addition to, or in place of, literal or surface-level meanings. Any particular instance of poetry is called a poem and is written by a poet. Poets use a variety of techniques called poetic devices, such as assonance, alliteration, euphony and cacophony, onomatopoeia, rhythm (via metre), and sound symbolism, to produce musical or other artistic effects. Most written poems are formatted in verse: a series or stack of lines on a page, which follow a rhythmic or other deliberate structure. For this reason, verse has also become a synonym (a metonym) for poetry.
Poetry has a long and varied history, evolving differentially across the globe. It dates back at least to prehistoric times with hunting poetry in Africa and to panegyric and elegiac court poetry of the empires of the Nile, Niger, and Volta River valleys. Some of the earliest written poetry in Africa occurs among the Pyramid Texts written during the 25th century BCE. The earliest surviving Western Asian epic poem, the Epic of Gilgamesh, was written in the Sumerian language.
Early poems in the Eurasian continent evolved from folk songs such as the Chinese Shijing as well as from religious hymns (the Sanskrit Rigveda, the Zoroastrian Gathas, the Hurrian songs, and the Hebrew Psalms); or from a need to retell oral epics, as with the Egyptian Story of Sinuhe, Indian epic poetry, and the Homeric epics, the Iliad and the Odyssey.
