In English, the word laureate has come to signify eminence or association with literary awards or military glory. It is also used for winners of the Nobel Prize and the Gandhi Peace Award.
In ancient Greece, the laurel (Laurus nobilis) was sacred to Apollo and as such sprigs of it were fashioned into a crown or wreath of honor for poets and heroes. This symbolism has been widespread ever since. "Laureate letters" in old times meant the dispatches announcing a victory; and the epithet was given, even officially (e.g. to John Skelton) by universities, to distinguished poets.
The name of "bacca-laureate" for a bachelor's degree shows a confusion with a supposed etymology from Latin bacca lauri (the laurel berry), which, though incorrect, involves the same idea. From the more general use of the term "poet laureate" arose its restriction in England to the office of the poet attached to the royal household, first held by Ben Jonson, for whom the position was, in its essentials, created by Charles I of England in 1617. Jonson's appointment does not seem to have been formally made as poet laureate, but his position was equivalent to that. The office was a development of the practice of earlier times, when minstrels and versifiers were part of the retinue of the King; it is recorded that Richard the Lionheart had a versificator regis (Gulielmus Peregrinus), and Henry III of England had a versificator (Master Henry); in the 15th century John Kay, also a versifier, described himself as Edward IV of England's "humble poet laureate." Moreover, the crown had shown its patronage in various ways; Chaucer had been given a pension and a perquisite of wine by Edward III of England, and Spenser a pension by Queen Elizabeth I. W. Hamilton classes Chaucer, Gower, John Kay, Andrew Bernard, John Skelton, Robert Whittington, Richard Edwards, Spenser and Samuel Daniel, as "volunteer Laureates."
