Which time period included the greatest masters of the renaissance?

The renaissance covered all the space from between the 14th and 17th centuries. This would approximately be from 1300-1600's.

Leonardo di ser Piero da Vinci was an Italian polymath, painter, sculptor, architect, musician, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer. He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived. His genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal. Leonardo has often been described as the archetype of the Renaissance Man, a man of "unquenchable curiosity" and "feverishly inventive imagination"
