Hi 82.196.42.196! Could you please assume some good faith here. The statement was placed there by some unknown and it was a mess. I have since try to work it so it's encyclopaedic. The story checks out. It was written by a British diplomat & writer from the 19 century called Andrew Archibald Paton (1811-1874). It’s on page 164 to 165 from his book "Researches on the Danube and the Adriatic". Also could you please provide references other than the bank vault. I can assure you there is no dubious references here. If you think Wikipedia is doing you a disservice please go through proper protocol. I myself don't real care as long it's encyclopaedic.  I'll check for spelling. Cheers!
