Bronze icons of Nataraja cast during the Chola period invariably show the deity with four hands. This depiction is based on the classical iconography of Lord Shiva as Nataraja, the Lord of Dance.

Option 1: Eight Hands - The depiction of Nataraja with eight hands is not accurate for the Chola period. The iconography of Lord Shiva with eight hands is commonly associated with the Ashtamurti form, where each hand holds a specific symbol or object representing different aspects of the deity. However, during the Chola period, the focus was on portraying Lord Shiva as Nataraja, the cosmic dancer, which is characterized by a specific set of attributes.

Option 2: Six Hands - The depiction of Nataraja with six hands is also not accurate for the Chola period. While the six-armed form of Lord Shiva is known as Sadashiva, the Chola bronze icons specifically represent Lord Shiva as Nataraja, emphasizing his role as the divine dancer and the cosmic force.

Option 3: Four Hands - This is the correct option. Bronze icons of Nataraja cast during the Chola period invariably show the deity with four hands. The four hands of Nataraja hold significant symbols that represent various aspects of Lord Shiva`s power and cosmic dance. In the upper right hand, Nataraja holds the drum (damaru), symbolizing the creation of sound and the universe. The upper left hand holds the fire (agni), representing the process of destruction and transformation. The lower right hand is in the abhaya mudra (fearlessness gesture), representing protection and dispelling fear. The lower left hand points towards the raised foot, symbolizing liberation and salvation.

Option 4: Two Hands - Nataraja is not depicted with two hands during the Chola period. While there are instances of Lord Shiva being depicted with two hands in other forms, such as the Ardhanarishvara (half-man, half-woman) or the Lingodbhava (emergence from the linga) forms, the Nataraja form specifically showcases the deity with four hands, as mentioned above.

The Chola dynasty, which ruled over a significant part of South India from the 9th to the 13th century, made remarkable contributions to the art and culture of the region. The bronze casting technique was highly developed during this period, and numerous bronze icons of Nataraja were created. These icons served as important religious and artistic representations, capturing the essence of Lord Shiva`s cosmic dance and the eternal cycle of creation, preservation, and dissolution. The Nataraja bronzes from the Chola period are considered some of the finest examples of Indian classical art, showcasing intricate details, graceful movements, and symbolic elements that convey profound spiritual meanings.
