Cento
Cento (Lat. cento, centonis, a patchwork; apparently from Gk. kentron, in the sense of a pin), a composition consisting of lines taken from various places in the works of one or more authors, so arranged as to make a poem with a continuous sense. Such "centos," especially from Virgil, were a common exercise of ingenuity in the later periods of Latin literature. The term is also applied to sets of musical selections.
