By some it has been contended that these masks covered both the head and the shoulders under the supposed idea that when the head was thus enlarged it would throw the whole body into symmetry when raised upon stilts. It has, also, been argued that the masks for some of the characters were made of gold-beaters skin, or some transparent substance just covering the face so that the facial muscles could be seen through it, and the eyes, mouth, and ears being left uncovered. These masks, however, delineated very carefully the features of the character that were to be represented. Something not unlike the huge Pantomime masks of a hideous and frightful shape that we sometimes see in our present day Pantomimes must have appeared, especially those that covered the head and shoulders of the _Mimis_ in the days of the Romans. Those that were just of the size of the face in all probability were fantastic and picturesque; and the third and remaining species of mask made of a transparent substance could hardly have been very effective. Mr. Wright tells us, in his book on the Chester Mystery plays (which work I shall again refer to later on), that masks were used in the Mystery series of plays acted in England during the thirteenth and fourteenth centuries. Julius Pollux is still more ample in his account of theatrical masks used in Tragedy, Satyr, and Comedy. Niobe weeping, Medea furious, Ajax astonished, and Hercules enraged. In Comedy, the slave, the parasite, the clown, the captain, the old woman, the harlot, the austere old man, the debauched young man, the prodigal, the prudent young woman, the matron, and the father of a family, were all constantly characterised by particular masks. Lucian and the other writers of the Augustan era, have handed down to us sufficient information to show how Pantomime in Rome was so highly thought of. Cassiodorous, speaking of them, says:--"Men whose eloquent hands had a tongue, as it were, on the tip of each finger--men who spoke while they were silent, and knew how to make a recital without opening their mouths--men, in short, whom Polyhymnia had formed in order to show that there was no necessity for articulation in order to convey our thoughts." Demetrius, a cynic philosopher, laughed at the Romans for permitting so strange an entertainment; but having been, with much difficulty, prevailed upon to be present at the representation of one of them, he was confounded with wonder. The story represented was that of Mars and Venus, the whole performed by a single actor, who described the fable in _dumb show_. At length the philosopher, wrought up to the highest pitch of admiration, exclaimed, "That the actor _had no occasion for a tongue, he spoke so well with his hands_."
