SYR'MA (σύρμα). A long robe trailing on the ground; more particularly worn upon the tragic stage (Juv. viii. 229.) by actors who performed the parts of divine or heroic personages, as in the annexed figure (Syrma/1.1), representing the character of Hercules, from a group of actors on a marble bas-relief. It was intended to give grandeur and dignity to the person, and conceal the unsightly appearance of the high-soled tragic boot (cothurnus) at the back of the actor.
