Shiva is the principal deity or “Moolavar” of the Brihadeeswarar Temple. All gods, including Dakshinamurthy and Surya, are gigantic, especially those positioned in the outer wall niches.
The “Ashta-dikpaalakas – Indra, Agni, Yama, Nirrti, Varuna, Vayu, Kubera, and Iana – were initially represented by a life-sized statue, approximately 6 feet tall, placed in a separate temple in the corresponding direction. The only remaining deities are Agni, Varuna, Vayu, and Iana. The temple’s main deities are Lord Brihadeeswarar and Goddess Periyanayaki.
