@izzythepush,
The presence of Eastern silk in Scandinavia's Viking Age grave sites has been known as well.
It seems that some Viking Age burial customs were influenced by Islam and the idea of an eternal life in Paradise after death.
The ideal of the Vikings was the warrior and the aim was victory. Therefore "the suffering Christ" on the cross was not received sympathetically amongst the Vikings, and perhaps some thought 'Allah' to be better.
"In the Quran, it is written that the inhabitants of Paradise will wear garments of silk, which along with the text band’s inscriptions may explain the widespread occurrence of silk in Viking Age graves,” Annika Larsson [researcher in textile archaeology at the Department of Archaeology and Ancient History at Uppsala University] said.
