One other ornament in the British Museum, particularly worthy of attention, is a beautiful set of three ornamental pins of silver gilt, which were found in the River Witham, near Lincoln. The three pins have heads in the shape of circular discs, and are connected together by two oblong pieces of metal with a ring at each end. The pins average four inches in length. The interlaced ornament on their circular heads (described in detail in the Reliquary, 2nd Series, Vol. X, p. 52), is arranged in four panels separated by radial divisions.
The penannular brooch, known as the Celtic brooch, so common in other parts of the British Isles about this period, has rarely been found in England. A few examples occur in close proximity to undoubted Anglo-Saxon remains, but they are confined mostly to the north of England. Its extreme rarity leads one naturally to the conclusion that it found but little favour in England. In Scotland and Ireland, however, where it was almost universally worn, this type of brooch attained, as will shortly be shown, the highest degree of excellence both in design and workmanship.
CHAPTER X
THE CELTIC BROOCH
IN order to understand the condition of the arts in the more remote parts of the British Isles, subsequent to the introduction of Christianity towards the middle of the fifth century, one must remember the situation created by the invasions of the Teutonic tribes, whereby nearly the whole of northern and western Europe relapsed into paganism, while Ireland and the western highlands of Scotland alone remained faithful to the Christian Church. During the earlier centuries of this period, the designs and processes of the Celtic crafts, nurtured in these parts of the British Isles by the Church, undisturbed by invaders, and free from outside influences, were brought to a state of high perfection.
The introduction of Christianity into Ireland by St. Patrick, who doubtless brought with him European craftsmen, had greatly encouraged the production of metal-work; and though changes in design resulted, the spiral patterns characteristic of Celtic art were retained for a considerable length of time—longer in fact than in any other quarters. It is unfortunate, however, that while a number of objects of early Christian art from Ireland and the Scottish highlands have survived, there is scarcely a single article of jewellery which is prior in date to about the ninth century a.d.
The chief personal ornaments belonging to this later period, i.e. the ninth century onwards, are a number of remarkable objects known as Celtic brooches. The Celtic brooch, as far as its origin and development are concerned, shows no kinship with the bow or disc-shaped brooches already described, though, like them, it probably originated among the primitive Celts of the Danubian region. One theory derives its evolution from what is known as a ring-pin, that is a simple pin, the head of which, primarily solid, was afterwards pierced and fitted with a ring, which in course of time increased in size and became highly ornamented. Another theory traces the Celtic brooch from a combination of a long pin with the ancient dress fasteners—penannular rings furnished with knobs—such as are found in prehistoric graves, and are even now worn by the natives of West Africa. This penannular brooch has been found not only in Scotland and Ireland, but as far east as Livonia, and is actually still in use in Algeria at the present day. Its peculiarity consists in the great size of its pin—one in the British Museum measures 22½ inches—the length of the pin being supposed to have corresponded to the rank of its owner.[24] In some of the earlier forms the ring is of the same breadth all round, and merely cut across in one place for the passage of the pin. But as a rule this penannular ring terminates in knobs, and when the pin which travels round the ring has pierced the portions of the garments it is intended to unite, the ring is pushed a little to one side and prevented by the terminal knobs from becoming unloosened.[25]
The developments in the form of this brooch show its evolution from a penannular to an annular ring. In some—probably the earliest—examples, the ring and the head of the pin terminate in bulbous knobs, or in spherical ends ornamented with Celtic designs and animals' heads. In others the ends of the rings and the pin-heads are broadened, in order to provide space for an elaborate surface decoration of interlaced work and zoomorphic and anthropomorphic designs similar to those upon the Irish manuscripts. Finally, the opening is closed and the ring becomes annular.
