Bront has recently pointed out to me that we don't have a thread on Russian folklore etc...
Other than a healthy Cold War interest in the Soviet Union (including the WWII era), I never paid much attention to Russia or Slavic matters in general. I'd seen Doctor Zhivago as a child and didn't really "get" it. I did learn about various aspects of early Slavic culture/folklore when I read Keith Taylor's classic Bard II: The First Longship, which had a substantial part take place along the Baltic coast. Its big villain was Taylor's take on Koschei the Deathless from Slavic myth. I thought KT had made up Koschei at the time.
I read CJ Cherryh's Rusalka at some point in the '90s. A link here:
Even my cousin (RIP) studying Russian to be a translator (we have no Russian background) didn't do much to spur my interest beyond a very low level. It took me reading Osprey's two books on medieval Russia, along with the publication of Harold Lamb's Cossack/Russian tales to get me fairly interested. That was around 2007. Even then, it was several years before I looked into much else concerning the Slavs and Russia.
Bront's right. Now's the time for a thread on this. We have similar ones on the Vikings, Native Americans, etc. Plus, we just had a Russian join the forum. Besides actual Slavic Russia, this thread will also (occasionally) look at pre-Slavic archaeology from the region of what is now modern Russia. The Russians have certainly taken the pre-Slavic site of Arkaim to their hearts.
