Explanation:

Warli painting is a style of tribal art mostly created by the Adivasis from the North Sahyadri Range in India.The simple pictorial language of Warli painting is matched by a rudimentary technique. The ritual paintings are usually created on the inside walls of village huts.These rudimentary wall paintings use a set of basic geometric shapes: a circle, a triangle, and a square. These shapes are symbolic of different elements of nature.
The circle and the triangle come from their observation of nature. The circle represents the sun and the moon, while the triangle is derived from mountains and pointed trees. In contrast,the square appears to be a human invention, indicating a sacred enclosure or a piece of land.Warli Painting is traditional knowledge and cultural intellectual property preserved across generations.
