Poetry as an art form predates literacy. In preliterate societies, poetry was frequently employed as a means of recording oral history, storytelling (epic poetry), genealogy, law and other forms of expression or knowledge that modern societies might expect to be handled in prose. The Ramayana, a Sanskrit epic which includes poetry, was probably written in the 3rd century BCE in a language described by William Jones as "more perfect than Latin, more copious than Greek and more exquisitely refined than either." Poetry is also often closely identified with liturgy in these societies, as the formal nature of poetry makes it easier to remember priestly incantations or prophecies. The greater part of the world's sacred scriptures are made up of poetry rather than prose.
