Leonardo Da Vinci (1942-1519) was a Florentine artist and well known for being a painter, sculptor, architect, engineer and scientist. The Mona Lisa, which should sound familiar, was drawn using two techniques Sfumato and chiaroscuro. Sfumato involves creating a hazy effect, while chiaroscuro involves a contrast of light and shade.
Vincent van Gogh (1853-1890), was a Dutch postimpressionist painter who painted landscapes and people (like most others). He began using swirling brush strokes, as well as much yellow, green and blue during his stay in Southern France.
