late 14c., "play in a cycle of mystery plays," from M.L. pagina, perhaps from L. pagina "page of a book" (see page (1)) on notion of "manuscript" of a play. But an early sense in M.E. also was "stage or scene of a play" (late 14c.) and Klein says a sense of L. pagina was "moveable scaffold" (probably from the etymological sense of "stake"). With excrescent -t as in ancient (q.v.). Generalized sense of "showy parade, spectacle" is first attested 1805, though this notion is found in pageantry (1650s).
