Viktor Vasnetsov and his brother Apollinarii were 19thC artists whose work helps bring to life historical Russia, and folkloric and mythic Russia, too. Viktor, for example, is well-known for his iconic picture of the Three Bogatyrs, above, while I especially like Apollinarii’s more technical depiction of the marketplace in Novgorod, below.
In any case, their work is a great inspiration of and for Mythic Russia, so here are some places to see more:
