Nataraja also known as Adalvallaan is a depiction of the Hindu God Shiva as the divine cosmic dancer. His dance is called Tandava. The pose and artwork are described in many Hindu texts such as the Tecarama, Thiruvasagam in Tamil and Anshumadbhed agama and Uttarakamika agama in Sanskrit and Grantha texts, the dance murti featured in all major Hindu Temples of Shaivaism, and is a well-known sculptural symbol in India and popularly used as a symbol of Indian culture, in particular as one of the finest illustrations of Hindu art. He is commonly referred as Koothan(ta: கூத்தன், romanized: Kūththaṉ), Sabesan(ta: சபேசன், romanized: Sabēsaṉ) and Ambalavanan (ta: அம்பலவாணன், romanized: Ambalavāṇaṉ) in various Tamil texts.
The sculpture is symbolic of Shiva as the lord of dance and dramatic arts, with its style and proportions made according to Hindu texts on arts. Tamil Devotional texts such as Tirumurai (The twelve books of Southern Shaivism) speaks that Nataraja is the form of Shiva in which he does Creation, destruction, Preserving, Maya and Blessing. Thus Nataraja is considered one of the highest forms of Shiva in Tamil Nadu, and thus sculpture or Brass idol of Nataraja is kept and worshiped in almost all Shiva temples across Tamil Nadu. It typically shows Shiva dancing in one of the natya Shastra poses, holding various symbols which vary with historic period and region, trampling upon a demon shown as a dwarf who symbolizes spiritual ignorance.
