DOSSUA´RIUSor DORSUA´RIUS, any animal carrying burthens on its back (Varr. R. R. 2.6 and 10). It carried its load either by means of panniers [CLITELLAE] or the packsaddles (sagma), whence we read of equus sagmarius (Lamprid. Heliog. 4; Vopise. Aur. 7). Hence came the German Saum-pferd and the English sumpter -horse. The annexed cut, representing a mule and a camel, carrying burthens, accompanied by two conductors, is taken from the Theodosian Column at Constantinople.
