Loculus is a Latin word literally meaning little place and was used in a number of senses including to indicate a satchel. Satchels were carried by Roman soldiers as a part of their sarcina or luggage. No loculus has survived in entirety although some small portions of leather found at Bar Hill (Strathclyde, Scotland) have tentatively been identified as parts of a loculus. The object is primarily known from illustrations on Trajan's Column. The loculus was probably used to store rations and a soldier's personal effects.
