Where did the renaissance start?
Between the 14th and 17th centuries, beginning in Florence and later spreading to the rest of Europe.
Leonardo da Vinci is considered the 'Father of the Renaissance'. Answer 2: No, Leonardo was considered the typical Renaissance man. He stands in the middle of the Renaissance, not at the start. Giotto di Bondone was called the father of the Renaissance. Nobody has ever called Leonardo this. (Except the above misguided answerer.)
The renaissance was a cultural movement. It included art, music, science... everything really. Your question isn't appropriate. Cultural movements happen because people start doing everything differently. So renaissance period people didn't start using art, art started changing along with everything else, in the 1300's.
