Concept:
In traditional Indian temple sculpture and idol making, the choice of stone is extremely important. Sacred sculptures intended for worship must be made from durable, stable, and spiritually appropriate materials according to traditional sculptural canons (Shilpa Shastra).
Step 1:
Common stones used for sacred sculpture include:
• Granite
• Soapstone
• Certain durable limestones
These stones are preferred because they:
• Are strong and long-lasting
• Resist weathering
• Allow detailed carving
• Maintain structural integrity
Step 2:
Aged stone refers to stone that has:
• Become weak over time
• Developed cracks
• Undergone weathering
• Lost structural strength
Such stone is considered unsuitable because:
• It may break during carving
• It cannot preserve fine details properly
• It lacks durability for sacred idols
• Traditional sculptural practices avoid damaged material
Therefore, aged stone should not be used for worship sculptures.
Step 3:
Option (1): Soap stone
Soapstone is widely used in temple sculpture because it is soft enough for detailed carving.
Option (2): Lime stone
Limestone has historically been used in architecture and sculpture.
Option (4): Granite
Granite is one of the most durable and sacred sculptural stones used in Indian temples.
Step 4:
Traditional Indian sculpture emphasizes:
• Purity of material
• Structural stability
• Ritual suitability
• Longevity of sacred icons
Hence, damaged or aged stones are avoided.
Step 5:
Since aged stone is structurally weak and unsuitable for sacred idol carving, the correct answer is:
