SPOLIA'RIUM. An undressing room, in which the arms and clothing were stripped from the gladiators who were slain in combat (Senec. Ep. 93. Lamprid. Commod. 18. and 19. Inscript. ap. Grut. 489. 12.); whence the term is also applied generally to any place in which a person is plundered or murdered. Senec. Prov. 3.

2. An undressing room in a set of baths (Gloss. Isidor.); same as APODYTERIUM; but this usage of the word rests upon no other authority than the one cited.
