Men's item of clothing to cover the abdomen (Varro, Ling. 6,21; Non. 29,17). Originally, it was probably worn under the Roman toga (Non. 29,17; Isid. Orig. 19,22,5) and was later replaced by the tunica . The subligar, on the other hand, is a cloth worn for special occasions, such as by actors (Juv. 6,70) and by women in the bath (Mart. 3,87,3), or generally by labourers (Plin. HN 12,59).
