I used to remember one artist who made drawings in historical settings more than a decade ago. One of his drawing was set on the British Isles during the Viking settlement with a Celtic thrall woman being exploited in some tavern. Perhaps the slavers were Anglo-Saxons, but the slave woman was Celtic and it was set in the Middle Ages before the Norman Invasion. I wonder if anyone remembers it and has more info on the artist and his/her work.
