Step 1: Identify the artist and artwork. K.G. Subramanyan was a versatile modern Indian artist known for working in a wide range of media. His murals are particularly famous.
Step 2: Recall the medium of his significant murals. One of K.G. Subramanyan's most celebrated mural techniques involved using individually fired terracotta tiles. He would paint on these clay tiles before firing them, and then assemble them to create large-scale murals.
Step 3: Connect the technique to the specific artwork. The mural "Three Mythological Goddesses" is a prime example of his work using thousands of small, painted terracotta tiles to create a vibrant and textured surface.
