phantasmagoria

1802, name of a "magic lantern" exhibition brought to London in 1802 by Philipstal, the name an alteration of Fr. phantasmagorie, said to have been coined 1801 by Fr. dramatist Louis-Sébastien Mercier, from Gk. phantasma "image" + second element probably a Fr. form of Gk. agora "assembly" (but this may have been chosen more for the dramatic sound than any literal sense). Transf. meaning "shifting scene of many elements" is attested from 1822.
