Theodor Kittelsen.
Probably best known for his pencil and charcoal pencil illustrations of trolls.
Painted some fantastic landscapes, scenes from folk tales and legends, silly pictures of animals and personifications of the black death.
I quite like this picture as I've been to the exact place depicted in it, and I can vouch for the accuracy maybe apart from the facelike aspect of the mountain side in the upper middle of the painting.
The following three are from a book with illustrations depicting the black death, same goes for the other pictures of the crone with the rake which is an anthropomorphic representation of the plague.
The forest troll
Huldra forsvant. A young man is sadly gazing out into a misty bog looking for a hulder (nordic forest spirit, a tusse, that can be either benevolent or malevolent, but almost always seductive. Similar to the jap kitsune spirits as they could have inhuman traits like either a cows tail or a foxes tail)
"An unfortunate bear hunt"
