The correct option is 1 and 3 only.
Explanation
In prehistoric rock art sites, such as the Bhimbetka rock shelters in Madhya Pradesh, archaeologists have observed multiple layers of paintings superimposed on one another. This phenomenon provides insights into the artistic process and cultural continuity of early humans.
Statement-wise Analysis:
- Statement 1 is Correct: According to archaeological interpretations (specifically noted in NCERT Fine Arts), one explanation for superimposition is that the artist may have been dissatisfied with their initial creation and chose to paint over it to improve or correct the imagery.
- Statement 2 is Incorrect: The superimposition is generally not attributed to a lack of space. Many rock shelters have ample surface area that remains unpainted. Instead, specific spots were likely reused because those particular locations were considered sacred or special by the community.
- Statement 3 is Correct: These sites were often inhabited or visited by humans over millennia. The superimposition suggests that the same area was used by different generations of people at different times, reflecting a continuity of tradition and ritual significance.
Key Takeaway:
Superimposition in prehistoric rock art is primarily attributed to the ritualistic significance of specific locations and generational continuity, rather than a scarcity of painting surface.
