The Cholas built in granite, but their most intimate art was poured in metal. Between roughly the 10th and 12th centuries, the delta workshops of Tamil Nadu produced bronze icons of gods and saints so alive with movement that they became the defining image of South Indian sculpture. The finest of them now stand a few steps from the Big Temple, in the Thanjavur Art Gallery.
- Cast by the lost-wax (cire perdue) method — each icon is unique; the mould is destroyed to release it.
- Made in an alloy called panchaloha, literally “five metals.”
- The 11th–12th centuries were the height of the art.
- Major collections sit in the Thanjavur palace Art Gallery and the Government Museum, Chennai.
A god you can only cast once
The method is called lost-wax casting, or cire perdue. The sculptor first models the full figure in a mix of beeswax and resin, working every detail — the fingers, the jewellery, the eyes — into the wax itself. The wax model is then packed in fine clay and fired; the wax melts and runs out, leaving a hollow mould, and molten bronze is poured into the space the god once occupied. To free the finished icon, the clay mould must be broken open. Because the mould is destroyed in the process, every Chola bronze is literally one of a kind — no two can ever be identical.
The dancing Shiva
The masterpiece of the tradition is Shiva as Nataraja, the lord of dance, caught mid-step inside a ring of flame that stands for the cycles of the universe. In one hand he holds the drum whose beat begins creation; another palm is raised in a gesture of protection; a foot presses down a small figure of ignorance while the other lifts, weightless. It is at once a religious icon and a compact diagram of a whole cosmology — and it is the form in which Chola metalwork is most often recognised around the world.
A craft that never stopped
What makes the Chola bronzes unusual among ancient arts is that the craft never died. In the town of Swamimalai, near Kumbakonam, families of sthapathis — traditional icon-makers, many of the Vishwakarma community — still cast bronzes by the same lost-wax method, following the proportions laid down in the Shilpa Shastra texts. In 2008 the “Swamimalai bronze icons” were given a Geographical Indication tag, legally protecting the name for icons made in that town by those methods. A traveller in the delta can therefore do something rare: see the medieval bronzes in the Thanjavur gallery in the morning, and watch a near-identical one being cast in a Swamimalai workshop the same afternoon.
Frequently asked questions
How were Chola bronzes made?
By the lost-wax (cire perdue) method: the figure is modelled in wax, packed in clay and fired so the wax melts out, then bronze is poured into the mould. The clay mould is broken to release the finished icon, so each bronze is unique.
What metal are they made of?
An alloy called panchaloha — literally “five metals” — traditionally combining copper with other metals such as gold, silver, brass and lead in varying proportions.
Where can I see Chola bronzes in Thanjavur?
In the Thanjavur Art Gallery (the Rajaraja Chola Art Gallery), inside the Maratha palace complex in central Thanjavur.
Are Chola bronzes still made today?
Yes. Sthapathis at Swamimalai, near Kumbakonam, still cast bronze icons by the lost-wax method; the “Swamimalai bronze icons” hold a Geographical Indication tag granted in 2008.
