recognition, but afterwards by imitating human features, these developed into masks. This custom continued, then, as sanctified by tradition, and, indeed, all the theatrical arrangements were regarded as a sacred ceremony in honour of Dionysus. The theatrical masks, the material of which in later times, too, was linen, covered with plaster of Paris, or else wood, bark, etc., differed from our modern masks in covering not only the face, but the whole head of the actor. The actor who had put on the mask could, of course, only see through the slits for the eyes, and, indeed, it sometimes happened--and in the oldest period seems to have been common--that, instead of cutting out a slit for the whole eye, there was only one for the pupil, and the iris was represented on the mask itself, and coloured, so that the actor had the difficult task of looking only through the place for the pupil; still, as the dimensions of the masks were usually larger than those of a human face, this may have been larger than his own. Of course, the masks were completely painted over; the eyebrows, lips, cheeks, wrinkles, etc., were marked; the beard and hair were made of real hair, or wool, or some other succedaneum. Some of the tragic masks had a high bunch of hair above the forehead to increase the height; this was called the “superficies” (onkos), and its object was mainly to increase the height of the actor and make him appear of greater size--an object at which many other peculiarities of the tragic costume also aimed. The ears were not always visible. The mouth was usually open, very wide, with lips and sometimes artificial teeth. The object of the great width of the mouth opening was to enable the actor to declaim and sing unhindered. The comic masks (see below, Figs. 156 and 157), very often had a funnel-shaped mouth opening, which gave a very grotesque expression to the whole face, and may have been connected with some special technical object, or else merely destined to increase the comic effect. In putting on the masks they took hold of the chin, and drew them on from bottom to top; they were then fastened under the chin with strings, and the actor’s neck was almost completely covered by the mask and his clothing; hence the curious, we might almost say asthmatic, impression given by the pictures of ancient actors. Generally speaking, we may distinguish three kinds of masks, according to the three kinds of drama--tragic, comic, and satyric; and it is not difficult among the numerous representations of masks on ancient works of art to distinguish between these three kinds, especially since the expression is, as a rule, decisive. In the tragic masks we see calm solemnity, deep grief, [Illustration: FIG. 154.] [Illustration: FIG. 155.]
