Literature
    Literature is the art of written works. Literally translated, the word means "acquaintance with letters" (from Latin littera letter). In Western culture the most basic written literary types include fiction and non-fiction
    The word "literature" has different meanings depending on who is using it. It could be applied broadly to mean any symbolic record, encompassing everything from images and sculptures to letters. In a more narrow sense the term could mean only text composed of letters, or other examples of symbolic written language (Egyptian hieroglyphs, for example). An even more narrow interpretation is that text have a physical form, such as on paper or some other portable form, to the exclusion of inscriptions or digital media. The Muslim scholar and philosopher Imam Ja'far al-Sadiq (702-765 AD) defined Literature as follows: "Literature is the garment which one puts on what he says or writes so that it may appear more attractive."[1] added that literature is a slice of life that has been given direction and meaning, an artistic interpretation of the world according to the percipient's point of views. Frequently, the texts that make up literature crossed over these boundaries. Russian Formalist Roman Jakobson defines literature as "organized violence committed on ordinary speech", highlighting literature's deviation from the day-to-day and conversational structure of words. Illustrated stories, hypertexts, cave paintings and inscribed monuments have all at one time or another pushed the boundaries of "literature."
    People may perceive a difference between "literature" and some popular forms of written work. The terms "literary fiction" and "literary merit" often serve to distinguish between individual works. For example, almost all literate people perceive the works of Charles Dickens as "literature," whereas some critics[citation needed] look down on the works of Jeffrey Archer as unworthy of inclusion under the general heading of "English literature." Critics may exclude works from the classification "literature," for example, on the grounds of a poor standard of grammar and syntax, of an unbelievable or disjointed story-line, or of inconsistent or unconvincing characters. Genre fiction (for example: romance, crime, or science fiction) may also become excluded from consideration as "literature."
    History
    One of the earliest known literary works is the Sumerian Epic of Gilgamesh, an epic poem dated around 2700 B.C., which deals with themes of heroism, friendship, loss, and the quest for eternal life. Different historical periods have emphasized various characteristics of literature. Early works often had an overt or covert religious or didactic purpose. Moralizing or prescriptive literature stems from such sources. The exotic nature of romance flourished from the Middle Ages onwards, whereas the Age of Reason manufactured nationalistic epics and philosophical tracts. Romanticism emphasized the popular folk literature and emotive involvement, but gave way in the 19th-century West to a phase of realism and naturalism, investigations into what is real. The 20th century brought demands for symbolism or psychological insight in the delineation and development of character.
    Poetry
    A poem is defined as a composition written in verse (although verse has been equally used for epic and dramatic fiction). Poems rely heavily on imagery, precise word choice, and metaphor; they may take the form of measures consisting of patterns of stresses (metric feet) or of patterns of different-length syllables (as in classical prosody); and they may or may not utilize rhyme. One cannot readily characterize poetry precisely. Typically though, poetry as a form of literature makes some significant use of the formal properties of the words it uses - the properties attached to the written or spoken form of the words, rather than to their meaning. Metre depends on syllables and on rhythms of speech; rhyme and alliteration depend on words
    Poetry perhaps pre-dates other forms of literature: early known examples include the Sumerian Epic of Gilgamesh (dated from around 2700 B.C.), parts of the Bible, the surviving works of Homer (the Iliad and the Odyssey), and the Indian epics Ramayana and Mahabharata. In cultures based primarily on oral traditions the formal characteristics of poetry often have a mnemonic function, and important texts: legal, genealogical or moral, for example, may appear first in verse form.
    Some poetry uses specific forms: the haiku, the limerick, or the sonnet, for example. A traditional haiku written in Japanese must have something to do with nature, contain seventeen onji (syllables), distributed over three lines in groups of five, seven, and five, and should also have a kigo, a specific word indicating a season. A limerick has five lines, with a rhyme scheme of AABBA, and line lengths of 3,3,2,2,3 stressed syllables. It traditionally has a less reverent attitude towards nature. Poetry not adhering to a formal poetic structure is called "free verse"
    Language and tradition dictate some poetic norms: Persian poetry always rhymes, Greek poetry rarely rhymes, Italian or French poetry often does, English and German can go either way (although modern non-rhyming poetry often, perhaps unfairly, has a more "serious" aura). Perhaps the most paradigmatic style of English poetry, blank verse, as exemplified in works by Shakespeare and by Milton, consists of unrhymed iambic pentameters. Some languages prefer longer lines; some shorter ones. Some of these conventions result from the ease of fitting a specific language's vocabulary and grammar into certain structures, rather than into others; for example, some languages contain more rhyming words than others, or typically have longer words. ............
