Spices were no more than a condiment. What made Venice fabulously rich was slave trade (12-16een cent.). High-profile slaves with languages (latin, greek,arab), blue-eyes blondes, such as Leonardo da Vinci's mother or Roxanne, Suleyman's favorite. Slave comes from Slave, from the Russian empire where all citizens were Tsar's slaves. High-profile slaves sold in Italy would become teachers for princes, that would, as rulers, support their activities.
