Theodor Kittelsen (1859-1914) was Norway's most famous illustrator from the golden age of illustration. These days he has a new following because several Norwegian black metal musicians are fans, and have put pictures like this one on their album covers. (Forest Troll, 1906)
As one online commenter put it, "Kittelsen and Dore both have been brought to the attention of new generations by the black metal romantics." Ah, yes, the black metal romantics. I suppose they must by the Byronic sort of romantics, not the twee Wordsworth kind. (The Hall of the Green Knight, and an album cover from Misanthropy Records)
Since he made his living illustrating Nowegian children's books Kittelsen spent a lot of time drawing silly trolls and goblins. Now nobody likes that stuff much, but his creepy and brooding stuff endures. (Nøkken, 1900 -- a sort of water spirit)
Kittelsen was one of eight children, and his father died when he was only ten. He was apprenticed to a watchmaker at 11, but his talent for drawing was recognized by a family friend, and he actually spent a while in Paris on a government scholarship. Perhaps he made friends with Symbolists. Some landscapes: Northern Lights, Twilight Lilypond.
He returned to Norway in 1887 and never left. He lived for a while in the Lofoten Islands (above), where he was much inspired by lonely lighthouses, fog shrouded cliffs, and that sort of thing.
Three illustrations from a little book on the Black Death, published in 1900.
Which of course have appeared on lots of album covers.
