A large part of my interest in the medieval fantasy that can be found in the games I mostly play (WFB, Dragon Rampant, my Averaigne Basic Fantasy/D&D campaign, Knights' Quest and various other dungeon-crawling games) is the combination of folkloric and chivalric legends. In some ways I'm quite Victorian in my enthusiasm for chivalry and its modern incarnations of gentlemanly conduct, while recognising the sometimes restrictive gendering aspects that don't sit well with some. I'm also a big fan of the works of painters such as Burne-Jones and other pre-Raphaelites, with their medievalism. When the two combine, I'm a happy man - and I've discovered a new artist that hits the spot that I wanted to share.
Katharine Cameron, a member of the Glasgow Art School in the late 1890s, worked as a book illustrator (among other things) and for me captures that slightly naive, watercolour/stained glass effect (I'm sure there's a proper artistic term for that). What caught my eye were these illustrations she did for Mary MacGregor's 1907 Stories of King Arthur's Knights that formed part of the Told to the Children series.
Lovely, aren't they? If you'd like to see them in context with their stories, the whole thing is available to read online as part of Project Gutenberg.
What other little known painters and/or illustrators do you know of that might appeal to me?
