F82r as the Black Sea

[R. Sale]

So, thinking about this a bit more, I'm pretty sure that there was someone sent out by Philip the Good who made that journey - north into the Baltic, down some Russian river (the standard trade route) into the Black Sea and back to the Mediterranean and to Burgundy. And it was earlier on - 1420 to 1440 - -  IIRC.

Didn't seem relevant at the time, but would have been in Richard Vaughan' s book on Philip the Good.
