Anything for the painting "And we are not afraid" by Nicholas Roerich?
My first thought was the Kalevala, the Finnish national epic! Tales of folklore would fit the colours of the painting, the otherworldly, magical feeling—and these long-bearded, cloaked, wizard-like figures facing each other remind me of Väinämöinen and Joukahainen’s singing contest / bard-off in the beginning, after their fender-bender:
Speaks the minstrel, Väinämöinen:
“Who art thou, and whence? Thou comest
Driving like a stupid stripling, [...]
Careless, dashing down upon me.
Thou hast ruined shafts and traces; [...]
And my golden sleigh is broken [...].
Then the boastful Joukahainen
Spake again to Väinämöinen:
“[...] He that is the sweeter singer,
He alone shall keep the highway,
And the other take the roadside.
Art thou ancient Väinämöinen,
Famous sorcerer and minstrel?
Let us then begin our singing, [...]
That the one may judge the other,
In a war of wizard sayings.”
I love epic poetry and never tire of it but I know it isn’t for everyone! May I also suggest (based on the bear and the snow and the building in the background): Our Land Was a Forest: An Ainu memoir by Kayano Shigeru, a really interesting look into Ainu history and culture and the author’s effort to preserve it. I knew nothing about Japan’s indigenous people before I read this book and it made me want to learn more.
Near the altar built to the east of Kaizawa Tomaat's house in Kohira, the thirty or so guests lined up [...]. Both men and women wore embroidered robes. Each man carried a sword from the shoulder, slung in front of the body. [...] The women covered their heads with black cloths folded in two, tied once behind their heads and draped down the back. In their left hands they held staffs. [...]
When, as in this case, someone drowns, the Ainu scolds the god of the river: "We have a victim because you were slack. You must endeavor to prevent such accidents in the future." Or if someone is burnt to death in a fire, the Ainu reprimands the goddess of fire, and when a bear mauls someone to death, not only the god of bears but the god of the mountains is reproved. In our Ainu world, humans and gods are perfectly equal; we do not consider the gods to possess absolute power.
