Here's a terrific review of the origins of modern art from Felipe Galindo for TedEd. It's called "how ancient art influenced modern art."
Galindo reviews the influence of traditional and ancient cultures on 20th century artists like Picasso, Gaugin, and Matisse.
He shows how ancient African culture influenced Picasso's seminal piece, "Les Demoiselles d'Avignon," which is considered to be the first 20th century masterpiece with new forms, colors, and meanings.
Pre-Columbian culture influenced other artisits. British sculptor, Henry Moore, for example, looked to the Toltecs for his inspiration.
This short clip is definitely worth bookmarking for next spring when we study the 20th century.
