In regard to technique, two points distinguish Athenian vases at all periods above other fabrics. Firstly, the admirable clay, traditionally obtained from Cape Kolias in Attica, and mingled with red ochre (rubrica) in order to produce its ruddy hue; this clay was eminently suited for taking a glaze, which was of course an essential preliminary for painting the surface. Next, the black varnish, with its exquisitely lustrous sheen, which was brought to a pitch of perfection in the subsequent period, and always affords such an admirable counterfoil to the red of the clay, though it has not been altogether popular with the modern photographer, owing to its reflecting qualities.

As regards the figures, they were seldom left entirely black, though black is at all times their prevalent aspect. The accessory whites and purples are used in varying degrees at different times, and it may be laid down as a general rule that purple is more affected on the earlier vases, white on the later. A like principle obtains with the accessories on red-figured vases. In the later examples, moreover, they are much more sparingly used, perhaps owing to the influence of the new technique, and by the end of the sixth century they disappear altogether. The more careful artists pay greater attention to the use of incised lines, and prefer to produce effects of richness and delicacy by elaboration of details and patterns in this manner.

At first there is a tendency to use purple in large masses, and even for the flesh of men; but it is generally employed for folds or portions of drapery, and for throwing up different parts of animals’ figures, or of the decorative patterns, such as palmettes and lotos-buds. White is employed for the hair of old men, for rocks and details of buildings, for the long garment worn by charioteers, and above all for the flesh of women. The latter we have already seen (p. [317]) to be an invention traditionally attributed to Eumaros, who probably lived about the middle of this century; but whether it was first introduced at Athens or Corinth is uncertain.

Throughout the period there is a steady advance in drawing, but more in the direction of carefulness and refinement than in accuracy and truthfulness to nature; that is to say, that it always remains conventional. We shall see later that, even after the red-figured style came in, a certain archaic stiffness still prevailed for a time, both in the old and new methods. On the other hand, there is a degenerate class of black-figured vases, found chiefly on Greek sites, in which the drawing is free almost to carelessness, and it is clear that these illustrate the last efforts of the black-figured method in Greece in the fifth century; but the vases are all rough and hasty productions, altogether devoid of merit or interest.

The treatment of drapery may generally be regarded as a fair indication of date. The chiton is at first straight, with rigid stripes or casual patches of purple; then patterns are incised or painted in white; the waist is usually very small, and often bound tightly with a broad girdle.[[1192]] By degrees the lines indicating the folds of the skirt take an oblique direction, as if to indicate motion, while the himation or mantle—which is adopted in addition by the women to wear over the chiton—is made to fall in long formal folds with diagonal edges, known as πτέρυγες. It is curious that the more advanced style of drapery is usually found on the red-bodied amphorae, the older types on the black-bodied. In the hydriae, which preserve the panel form of decoration throughout, a progress is visible from the most rigid severity to comparative freedom.

The shapes most frequently employed by Athenian potters are very limited in number—as, for instance, when compared with the Corinthian and other earlier fabrics. The really popular forms are limited to five: the amphora, hydria, kylix, oinochoe, and lekythos. Besides these we find the krater (usually with columnar handles), the deinos, the skyphos or kotyle (with its variant the mastos), the kyathos, the pyxis, and the pinax, and occasionally also the alabastron; but these are practically all. Some of these remain constant throughout, but others in their form and system of decoration present interesting varieties of development. In all cases there is an evident aim at improving upon the somewhat inartistic Corinthian forms, in the direction of grace, lightness, and architectonic symmetry.

The different types of Attic amphora have been described elsewhere (p. [160]), but may be briefly recapitulated here.

(1) The so-called Tyrrhenian amphora, found in the Corintho-Attic and “affected” varieties, with elliptical body (Plates [XXIII]., [XXIX].).

(2) The panel-amphora, with cylindrical handles.
