(in English, glose;gloss)
A poem composed as an amplification of lines taken from an earlier and usually better-known poem, although not literally as a gloss in the explanatory sense. The standard form begins with a sequence of lines—commonly a quatrain—from the source-poem, following this with a sequence of stanzas each ending with one (in variant forms, two) of these lines in succession. The term is Spanish, this kind of poem having been devised by Spanish courtiers in the early 15th century. There are English examples in the recent work of the American poet Marilyn Hacker, whose Essays on Departure (2006) includes poems entitled ‘Glose’, all developing four quoted lines from earlier poets into four rhymed stanzas.
