HISTORY OF EUROPEAN JEWELLERY The Empire of Rome, which had extended to the Rhine, the Danube and the Scottish frontier, and the trade of Rome, which had passed beyond these limits through Bohemia to the northern countries, left behind them a tradition so strong that it long outlived the Roman empire itself. In all this region the form, technique and decoration of jewels were influenced by Roman usage. The use of gold filigree remained general; and the varied Roman fibula forms became the basis of yet more complicated brooches. The most important development was in the use of thin slices of garnet set like enamel in metal cells (Plate A 2, 4, 7, 8), a technique ultimately derived from Egypt and probably transmitted through the Crimea. It is represented in the great 4th-century treasure found at Petrossa, 6o m. from Bucharest, and appears to have been in use nearly all over Europe between the 3rd and 8th centuries A.D. At the same time under Byzantine in fluence cloisonné enamel (see ENAMEL) was used for exceptional pieces, such as the famous Alfred jewel (Plate A, 1-3). This com mon tradition, however, was modified by each of the great Euro pean tribes into a style characteristic both in design and technique. Thanks to the general custom of burying their jewels with the dead these types of jewellery are well represented in European museums.


In Norway, too, fibula types of the 4th, 5th and early 6th centuries are derived from Roman or Crimean Gothic originals but after about 55o the types become national. The Scandinavian "tortoise" and trefoil brooches are entirely characteristic ; the former date from the 7th to the early I 1 th century, while the latter are characteristic of the 9th and loth centuries. These and cognate circular brooches (Plate I., fig. 5) are generally decorated with symmetrical designs of considerable beauty. The relations between Scandinavia and Ireland in the 8th and 9th centuries brought in the type of penannular brooch which in its attenuated northern form is characteristic of the Viking age.
