the wealth that he might thus have secured must have added prodigiously to the force of his arms by sea and land. A colossal military empire upon the Bosphorus, commanding the avenues of Asiatic trade, might even in our own days overawe half Europe, and would have been irresistible three hundred years ago.

When Benbo, the Venetian envoy at Lisbon, wrote that he had seen vessels return to that port from Asia loaded with Indian goods, his government became aware that the most important branch of their commerce was in danger of being cut off.
