CELEUS'MA (κέλευσμα). The chaunt or cry given out by the cockswain (hortator, pausarius, κελευστής) to the rowers of the Greek and Roman vessels, in order to aid them in keeping the stroke, and encourage them at their work. (Mart. Ep. iii. 67. Rutil. i. 370.) The chaunt was sometimes taken up, and sung in chorus by the rowers, and sometimes played upon musical instruments. Auson. in Div. Verr. 17.
