A term from Greek Platonic philosophy that meant a copy of a copy of an ideal form. In postmodernist thought, particularly through the writings of Gilles Deleuze and Jean Baudrillard, the term has been revived in the context of arguments about the relationship between an original work of art and its replication. For Baudrillard the simulacrum takes precedence over the original, with the effect that the original is no longer relevant.
