The architecture of India is rooted in its history, culture and religion. From at least 3000 B.C. to the present day, many civilizations have flourished on the subcontinent of India. Each has made valuable contributions to India's rich artistic heritage. The book begins with the study of ancient civilization and rock-shelter drawings. The book focuses mainly on art and architecture of early civilization. Indian art consists of a variety of art forms, including painting, sculpture, pottery, and textile arts such as woven silk. Geographically, it spans the entire Indian subcontinent, including what is now India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan and eastern Afghanistan. A strong sense of design is characteristic of Indian art and can be observed in its modern and traditional forms.
