The ornamented vases produced in these potteries are, as we have said, almost confined to two or three varieties, which follow one another chronologically. A shape favoured at first is the krater, which has been mentioned as one of the characteristic Arretine forms; but this enjoyed but a short term of popularity. Early in the 1st century we find a typical form of bowl in use, which, following the numeration of Dr Dragendorff’s treatise, is usually spoken of as No. 29. This is characterized by its moulded rim engraved with finely incised hatchings, and by the division of the body by a moulding into two separate friezes for the designs (fig. 36). Its ornament is at first purely decorative, consisting of scrolls and wreaths, then small animals and birds are introduced, and finally figure subjects arranged in rectangular panels or circular medallions. About the middle of the century a second variety of bowl (known as No. 30; see fig. 37) was introduced; this is cylindrical in form, and, being found both at Graufesenque and Lezoux, may be regarded as transitional in character. In the latter half of this century a new form arises (No. 37; fig. 37), a more or less hemispherical bowl which holds the field exclusively on all sites down to the termination of the potteries. In this form and in No. 30 a new system of decoration is introduced, the upper edge being left quite plain. The panels and medallions at first prevail, but are then succeeded by arcading or inverted semicircles enclosing figures, and finally after the end of the 1st century (and on form 37 only) we find the whole surface covered with a single composition of figures unconfined by borders or frames of any kind, but in a continuous frieze; this is known as the “free” style (Plate IV. fig. 69).

Fig. 37.—Shapes used in Roman Pottery. 1-11, Arretine; 18-65, Gaulish and German.

As regards the figure subjects, it may be generally laid down that the conceptions are good, but the execution poor. Many are obvious imitations of well-known types or works of art, and the absence of Gaulish subjects is remarkable. They include representations of gods and heroes, warriors and gladiators, hunters and animals, the two latter classes being pre-eminently popular.

The potters’ names at Graufesenque are nearly all of a common Roman type, such as Bassus, Primus, Vitalis; those at Lezoux are Gaulish in form, such as Advocisus, Butrio, Illixo or Laxtrucisa. This seems to imply that Roman influence was still strong in the earlier centre which drew its inspiration more directly from Arretium. But even the purely Roman names are sometimes converted into Gaulish forms, as Masclus for Masculus, or Tornos for Turnus. The stamps are quadrangular in form, depressed in the surface of the vase with the letters in relief; on the plain wares they are usually in the centre of the interior, but on the ornamented vases are impressed on the exterior among the figures. The usual formula is OF (for officina) or M (for manu) with the name in the genitive, or F, FE or FEC for fecit with the nominative.

Besides the ordinary terra sigillata with figures produced in moulds we find other methods of decoration employed. In the south of France, about Arles and Orange, vases were made with medallions separately moulded and attached round the body; these have a great variety of subjects, both mythological and gladiatorial or theatrical, or even portraits of emperors. There is a remarkable specimen in the British Museum with a scene from the tragedy of the Cycnus, on which Heracles and Ares are represented, with seated deities in the background (Plate IV. fig. 67). The date of these reliefs is the 3rd century after Christ.

Of the same date is a somewhat similar ware made at Lezoux. Here each figure is attached separately to the vase, and the background is filled in with foliage produced by the method known as en barbotine (slip-painting), of which we shall speak presently. The effect of these vases, which are mostly large jars or ollae (Plate IV. fig. 70), is often very decorative, and there is a fine specimen in the British Museum from Felixstowe, on which the modelling is really admirable. Other good examples have been found in various parts of Britain.

The “slip-decoration” process is practically unknown in Italy, but it is found early in the 1st century of our era in Germany, and appears to have originated in the Rhine district. It is not confined to the red ware, but in the early German examples is applied on a dull grey or black background. On the continent its use is almost limited to simple decorative patterns of scrolls or foliage, but in Britain it was largely adopted, as in the well-known Castor ware made on the site of that name (Durobrivae) in Northamptonshire. Many of the vases found or made here have gladiatorial combats, hunting-scenes, or chariots executed by this method (fig. 38). The decoration was applied in the form of a thick viscous slip, usually of the same colour as the clay, but reduced to this consistency with water, and was laid on by means of a narrow tube or run from the edge of a spatula. The Castor ware appears to date from the 3rd and 4th centuries a.d.

Painted wares are at all times rare, but were occasionally produced in Gaul, Germany and Britain. A notable class of such ware seems to have been produced in the Rhine district, represented by small jars covered with a glossy black coating, on which are painted in thick white slip inscriptions of a convivial character, such as BIBE, REPLE, DA VINUM, or VIVAS (Plate IV. fig. 68). A very effective ware, obviously imitating cut glass, by means of sharply incised patterns, was made at Lezoux in both the red and black varieties.
