The beautiful vessel at Fig. 101, found in a Roman sepulchre in the Bartlow Hills, in Essex, is a fine example of this early enamel. Other existing specimens of the Gallo-Roman period are in the Museum at Poitiers, in the Imperial Library, Paris, and in the Museums of London. From the Gallo-Roman period until the eleventh century most of the arts were at a low ebb, owing to the devastating wars and invasions that spread all over Europe; the art of enamelling had been almost lost, and had quite died out in France and Germany, but is likely to have still been practised in Ireland, where no doubt the art of the goldsmith and the enameller in conjunction had flourished less disturbed than in France or England. We have existing remains of pure Irish Celtic work that date from the ninth and probably earlier centuries, and are of unsurpassed workmanship. Chalices, books of the Gospels, croziers, reliquaries, brooches, jewellery, &c., more or less enamelled, were made in the ninth century, and some earlier. Ireland had a school of living art when in the ninth and tenth centuries the rest of Christendom was sitting wrapped in chaotic gloominess, idly awaiting the supposed end of the world, in A.D. 1000. As regards our present subject, we must notice as coming under the head of enamels that beautiful Irish relic known as the Ardagh Chalice. (Fig. 102.) The body of the cup is silver with about one-third or one-fourth of copper alloy. It is a wonderful mixture of metals, there being gold, silver, copper, bronze, brass, and lead; and an iron bolt secures the stem and bowl together. The ornaments are belts, and the handles, to which are fastened the beautifully designed and worked interlacings of Celtic ornament, of which each little panel is different; it is said that forty distinct varieties in the designs can be traced, consisting of interlaced bands of Celtic twistings, knots, and arabesques: each compartment of the principal belt of ornament is divided by a boss, or enamelled bead, of which there are twelve. The handles are composed of enamels and filigree work similar to the work of the belt, but different in design, with blue glass or paste bosses. The two larger circular ornaments on the sides are composed of gold filigree with a central enamelled boss. The four settings of these ornaments had two pieces of blue glass paste and two pieces of amber, which have fallen out. [Illustration: Fig. 102.—The Ardagh Chalice; Irish Celtic Work.

The circular foot is ornamented with gold and bronze plaques alternating on the outer rim; the bronze divisions are enamelled.
