Warli Painting:
The name of the painting comes from the people who have been carrying the painting tradition that goes back to 2500-3000 BC. They are called the Warlis, indigenous people that occupy mainly the Gujarat-Maharashtra border. These paintings have close resemblance to the mural paintings of Bhimbetka in Madhya Pradesh that date back to the pre-historic period. These ritualistic paintings have a central motif of a chaukat or chauk, which is surrounded by scenes portraying fishing, hunting, farming, dances, animals, trees and festivals. Among the Goddesses, Palaghata (goddess of fertility) is drawn and among the male gods, those spirits that have taken human form are represented.
Traditionally, the paintings are done on the walls using very basic graphic vocabulary, including a triangle, a circle and a square. These shapes are inspired from nature, i.e. circle from sun or moon, triangle from conical shaped trees or mountains and square from sacred enclosure or piece of land. To represent a human or animal, two triangles are joined at the tip, with circles acting like their head. The base is made of a mixture of mud, branches and cow dung that gives it a red ochre colour. For painting only white pigment is used, which is made of a mixture of gum and rice powder.

Towards the beginning of the twentieth century a new hybrid architectural style developed which combined the Indian with the European. By integrating Indian and European styles in public architecture the British wanted to prove that they were legitimate rulers of India. This was called Indo-Saracenic. The inspiration for this style was medieval buildings in India with their domes, chhatris, jalis, and arches. The Gateway of India, built in the traditional Gujarati style to welcome King George V and Queen Mary to India in 1911, is the most famous example of this style.
