Demid Pyanda 

Hi. You wouldn't happen to know of any English sources that speak of Pyanda (or Penda, as I've seen it spelled a couple times) in depth? I just bought Eastward to Empire, which I hope will answer some of my questions. From his article his explorations appear to be very dubious, seeing as how the only information on his expeditions is from hearsay over a century after the fact. Do you know of any primary documents that support his discoveries?
