The correct option is 2 and 3 only.
Explanation
The Rajasthani schools of miniature painting are broadly divided into various sub-schools based on princely states, each exhibiting distinct stylistic features ranging from indigenous boldness to Mughal-influenced refinement.
- Statement 1 is Incorrect: The Mewar school of painting is considered one of the most conservative and indigenous schools of Rajasthan. It is characterized by the use of bright and brilliant colours, particularly red and yellow. The backgrounds often feature bold patches of these vibrant colours to create emotional resonance. Therefore, claiming a "complete absence" of these colours is factually wrong.
- Statement 2 is Correct: The Bikaner school developed under the patronage of rulers who had close political relations with the Mughal court (e.g., Raja Rai Singh). Consequently, the Bikaner style reflects a strong Mughal influence. Unlike the bold and contrasting colours of Mewar, Bikaner paintings typically employ a subdued colour palette and finer lines, mirroring Mughal elegance and naturalism.
- Statement 3 is Correct: A distinguishing feature of the Bikaner school is the practice of inscribing the artist's name and the date (Samvat) on the paintings. This is relatively rare in other Rajasthani schools, where works often remained anonymous. Prominent artists like Ali Raza and Ruknuddin are well-documented due to this tradition.
Key Takeaway: The Mewar school represents the bold, chromatic, and indigenous style of Rajasthani painting, whereas the Bikaner school is noted for its Mughal-influenced subtlety and the unique archival tradition of signing and dating artworks.
