The furniture of Greek houses was simple, but full of artistic beauty. This was particularly displayed in vessels for the keeping of both dry and fluid stores, as were found in temples, dwellings and even graves. Only the last-mentioned have been preserved to us. Earthen vessels are the most numerous. The invention of the potter's wheel is of great antiquity, and was ascribed by the Greeks in different places to different mythical persons. The Corinthians named Hyperbion as its inventor. In the Kerameikos, the potters' quarter of Athens, Keramos, the son of Dionysos and Ariadne, was worshiped as such. The name of the locality itself was derived from this "heros eponymos." Next to Corinth and Athens (which latter became celebrated for earthen manufactures, owing to the excellent clay of the promontory of Kolias), Ægina, Lakedæmon, Aulis, Tenedos, Samos and Knidos were famous for their earthenware. In these places the manufacture of painted earthenware was concentrated; thence they were exported to the ports of the Mediterranean and the Black Sea for the markets of the adjoining countries. Owing to the beautiful custom of the ancients of leaving in the graves of the dead the utensils of their daily life, a great many beautiful vessels have been preserved which otherwise would have shared the destruction of the dwellings with much less fragile implements. From the pictures on these vases we derive, moreover, valuable information as to the public and private habits of the Greeks. The greatest number of graves in their original condition, and filled with vessels, are found in Italy. [Illustration: PLUNDERING CORINTH.] Good, particularly red, clay was in demand for superior goods, and of this the promontory of Kolias, near Athens, furnished an unlimited supply. The potter's wheel was in use at a very early period. On it were formed both large and small vessels, with the difference, however, that of the former the foot, neck, and handles were formed separately, and afterwards attached, as was also the case in small vessels with widely curved handles. In order to intensify the red color the vessel was frequently glazed and afterwards dried and burnt on the oven. The outlines of the figures to be painted on the vase were either cut into the red clay and filled up with a brilliant black varnish, or the surface itself was covered with the black varnish up to the contours, in which case these stood out in the natural red color of the clay. The first mentioned process was the older of the two, and greater antiquity is, therefore, to be assigned to vessels with black figures on a red ground. In both kinds of paintings draperies or the muscles of nude figures were further indicated by the incision of additional lines of the color of the surface into the figures. Other colors, like dark red, violet, or white, which on close investigation have been recognized as dissolvable, were put on after the second burning of the vessel.
