Incan artists used geometry in their artwork and architecture to convey strength. In power between 1350 and 1532 A.D., Incan rulers expanded their territory and eventually became the largest empire in the world. The Inca built Machu Picchu, a city high in the Andes, using cut stones. Textiles were their most valued artworks, and the geometric patterns woven into Incan textiles each have a specific meaning. The images painted on vessels often include stylized and abstract motifs, but never include narratives. Incan artists used gold to represent Inti, the Incan god of sun and the military, because they believed gold was the sweat of the sun.
