The correct option is 2 and 3 only.
Explanation
The Vesara style of temple architecture is a distinct hybrid style that combines elements of both the Nagara (North Indian) and Dravida (South Indian) architectural traditions. It emerged and flourished primarily in the Deccan region.
Statement-wise Analysis:
- Statement 1 is Incorrect. The Vesara style is not a pure form of the Dravida style. It is an independent style often referred to as the "hybridized style" because it integrates the plan and shape of the Nagara style with the intricate ornamentation and tiered arrangements of the Dravida style. The pure Dravida style is predominantly found in Tamil Nadu.
- Statement 2 is Correct. The Vesara style is primarily found in the Deccan region, specifically in present-day Karnataka. It was patronized extensively by the later Chalukyas (Chalukyas of Kalyani) and the Rashtrakutas.
- Statement 3 is Correct. The temples built by the Hoysala rulers (such as those at Belur, Halebidu, and Somnathpura) are widely considered the culmination of the Vesara style. While they possess unique features like the star-shaped ground plan (stellate plan), they are structurally classified under the Vesara tradition due to the blending of Northern and Southern influences.
Key Takeaway:
The Vesara style is a hybrid architectural form combining Nagara and Dravida features, prevalent in the Karnataka region under the patronage of the Chalukyas and Hoysalas.
