The vases found at Athens and other parts of Greece were also, as a rule, found in tombs and burial-places; one class in particular—the Athenian _lekythi_—were made specially to contain the sacred oil or wine and to be afterwards placed in the tomb. These vases are of a long, narrow, and elegant shape, and were decorated with appropriate funeral subjects outlined on a white ground. This white ground is known as _matt_, and is of a dull surface; it is not a glaze, but simply an engobe of clay fired at a very low temperature. The draperies of the figures are occasionally coloured red, brown, pale green, or a bluish tint, and some of them are remarkable for their beauty of drawing and expression of sentiment in the design. They date from B.C. 450 to 350. Greek vases are characterized by their beauty of shape as well as by their refined decoration. Some of the richly decorated ones were given as prizes to the victors in the Olympian games, and it has also been conjectured that some of the terra-cotta vases found in the tombs were designed to represent the costlier metal vases that were offered for prizes at the games held in honour of princes at their death, the coarser terra-cotta vases being used at the death of the common people. The shapes of the Greek vases vary in the different periods, getting more elegant as they approached the middle period—the fifth and the first half of the fourth century B.C.—and larger in size with the handles more elaborate in the later periods. The principal varieties are known under the following names:—the Amphora, a full-bodied vase with two handles, used for carrying wine; the Hydria, a wider bodied vase, used for carrying water: it has generally one large and two smaller handles; the Crater, a large wide-mouthed vessel, used for mixing wine and water; the Lebes, a round basin usually placed on the top of a stand or tripod; the Oinochoè, a ewer-shaped vase, used for pouring out wine; the Lekythos, a long bottle-shaped vase, used for holding oil; the Aryballos, for perfumes or oil; the Cantharos, a two-handled cup on a foot, used for drinking purposes; the Kylix, a shallow cup on a foot, used for drinking wine; and the Rhyton, or drinking horn, made in the shape of an animal’s head or a sphinx. Greek Ceramic ware, like the Etruscan and Roman, was coated with a scarcely perceptible thin glaze, supposed to be composed of a vitreous alkaline that merely hardened the clay body and left a very faint polish on the surface.
