In Celtic cultures, a bard is a professional story teller, verse-maker, music composer, oral historian and genealogist, employed by a patron (such as a monarch or chieftain) to commemorate one or more of the patron's ancestors and to praise the patron's own activities. With the decline of a living bardic tradition in the modern period, the term has loosened to mean a generic minstrel or author (especially a famous one). For example, William Shakespeare and Rabindranath Tagore are respectively known as "the Bard of Avon" (often simply "the Bard") and "the Bard of Bengal". In 16th-century Scotland, it turned into a derogatory term for an itinerant musician; nonetheless it was later romanticised by Sir Walter Scott (1771–1832). Source: Wikipedia (en)
