in the Stuttgart Psalter, Utrecht Psalter, Lothar Gospels and Bern Psychomachia manuscripts, as well as in the wall frescoes in the church in Mals, South Tyrol. Likewise, the custom of inlaid inscriptions in the blades is Frankish innovation dating to the reign of Charlemagne, notably in the Ulfberht group of blades, but continued into the high medieval period and peaking in popularity in the 12th century. While blade inscriptions become more common over the Viking Age, the custom of hilt decorations in precious metals, inherited from the Merovingian sword and widespread during the 8th and 9th centuries, is in decline over the course of the 10th century. Most swords made in the later 10th century in what was now the Holy Roman Empire, while still conforming to the "Viking sword" type morphologically, have plain steel hilts. Trade The distribution of Frankish blades throughout Scandinavia and as far east as Volga Bulgaria attest to the considerable importance of Frankish arms exports, even though Carolingian kings attempted to prevent the export of weapons to potential enemies; in 864, Charles the Bald set the death penalty on selling weapons to the Vikings. Ibn Fadlan in the 10th century notes explicitly that the Volga Vikings carried Frankish swords. The Saracens raiding Camargue in 869 demanded 150 swords as ransom for archbishop Rotland of Arles. Foreign-made, specifically Frankish, weapons and armour played a special role in Norse society. Norsemen attained them either through trade (an extension of gift-giving in Norse society) or as plunder. Therefore, their possession and display by any individual would signify their station in the social hierarchy and any political allegiances they had. One example of an exchange of weapons between the Franks and the Anglo-Saxons occurred in 795 when Charlemagne exchanged weapons with the Anglo-Saxon king Offa of Mercia. Scandinavian affinity towards foreign arms and armour during the Viking Age had an eminently practical aspect. Norse weapon designs were obsolete and sources of iron within Scandinavia were of poor quality. Many of the most important Viking weapons were highly ornate—decorated lavishly with gold and silver. Weapons adorned as such served large religious and social functions. These precious metals were not produced in Scandinavia and they too would have been imported. Once in Scandinavia, the precious metals would have been inlaid in the pommels and blades of weapons creating geometric patterns, depictions of animals, and (later) Christian symbols. During the mid-9th century,
