From Chapter 68 of the Decline & Fall

Ismael Beg, prince of Sinope or Sinople, was possessed (chiefly from his copper-mines) of a revenue of 200,000 ducats (Chalcocond. l. ix. p. 258, 259 [p. 489, ed. Bonn]). Peyssonel (Commerce de la Mer Noire, tom. ii. p.100) ascribes to the modern city 60,000 inhabitants. This account seems enormous: yet it is by trading with a people that we become acquainted with their wealth and numbers.
