The presence of the trumpet pattern upon the backs of these two famous brooches determines their date as prior to the eleventh century; for the old Celtic pattern disappears from brooches and from most Irish and all Scottish metal-work after the year 1000 a.d., and is succeeded by varieties of interlaced work and zoomorphic designs.[26] The later Celtic brooches differ besides in form, for the pin is longer in proportion to the size of the ring, and its head is hinged upon a constriction of the ring, which itself becomes partly filled up.
The Celtic brooch is distinct in itself, and does not merge into any other form. It disappears entirely about the thirteenth century, and is succeeded by a totally different type of brooch, which belongs to the ornaments of the later Middle Ages.
THE JEWELLERY OF THE MIDDLE AGES
(TENTH TO FIFTEENTH CENTURIES)
[CHAPTER XI]
MEDIÆVAL JEWELLERY
INTRODUCTION
TO the student of jewellery the Middle Ages offer far greater problems than the periods of classic antiquity. The main reason for this is to be found in the fact that throughout mediæval and later periods ornaments were more closely associated with dress, and dress itself became subject to the most marked changes and constant divergences of fashion. In the days of antiquity, so far as our knowledge goes, the idea of fashion, in the present sense of the term, did not exist. But in the Middle Ages, as Luthmer points out, it becomes an important factor in the history of civilisation. The duration of each prevalent fashion tended to become shorter and shorter, and the new mode was usually an absolute contrast to the preceding one. Though ornaments, owing to their higher material value, did not alter with each successive change in dress, nevertheless they underwent rapid variations of style.
The custom of burying objects in graves, which continued for a considerable time after the introduction of Christianity, affords a tolerably clear idea of the various ornaments worn during the earlier periods of the Middle Ages. Coming to a later period, from the time of the first Crusade onwards, discoveries in the graves are extremely rare, and one has to look in many directions for information respecting the articles then in use. Though there seems to have been an immense production of personal ornaments throughout the whole of Europe, their intrinsic value has been too great to allow of their preservation; and the artistic qualities of those that have survived cause one to regret all the more the wholesale destruction that must have occurred. The jewels of the period are, in fact, so few in number, and furnish such striking varieties, that it is impossible to give an exhaustive synopsis of the different changes that took place in their form. The utmost that can be attempted is to take single characteristic pieces and allow them to stand as types of the whole epoch.
