Fintan of Rheinau

[1] He himself was enslaved by the Vikings (possibly handed over by his Irish enemies[3]) and taken to the Orkney Islands, but was able to escape to Scotland.

[1] From there he went to the monastery of Farfa where he lived as a monk for some time, then via Rhaetia to Swabia, or to the landgraviate of Klettgau, where he entered the service of the Alemannic nobleman Wolvene.

[1] Shortly after his death, the Vita Findani was written by a confrere of the monastery; it is considered reliable.

[1] His biography, the Vita Findani, is considered to be a relatively accurate description of the Viking Age slave trade.

Interwoven with the story of Melkorka from the Icelandic Laxdaela-Saga, it has been the basis of the Austrian-German-French documentary "Victims of the Vikings" (ORF/ZDF/Arte 2021).
