The marvels of Indian art can be found in the relics of the temple, as well. Ancient Indian sculptures are a mix of artistic talent and mental excellence. Older empires who have ruled this country have left behind miraculous creations which not only have Indians but have left spellbound outsiders. The time during which these sculptures were built had limited scope of manpower and reference of ideas. One of the oldest optical illusions in the world is found in the Airavatesvara temple in Thanjavur, Tamil Nadu.
