Fernao Nuniz, was a
Portuguese traveler, chronicler and horse trader who spent three years in
Vijayanagara, capital of the
Vijayanagara Empire in the time period 1535-1537 CE. His writings have brought to light many interesting details about Vijayanagara at that time, including construction of massive fortification works, watch towers and security walls.
