The correct option is 2 only
Explanation
Prehistoric rock paintings, such as those found in the rock shelters of Bhimbetka, are often discovered in locations that are difficult to access, including high walls and ceilings. The placement of these artworks provides archaeological insight into their purpose.
Statement 1 is Incorrect: The creation of paintings in uncomfortable and difficult-to-reach positions suggests that these works were not intended for casual viewing or mere decoration. Instead, the effort required to paint in such locations indicates that they held ritualistic or special significance and were likely created during specific ceremonies or special occasions.
Statement 2 is Correct: While some prehistoric art in deep caves (particularly in Europe) suggests secrecy, Indian rock shelters are generally open and exposed to natural light. The primary academic explanation for the specific placement on high ceilings in this context is the sanctity or ritual importance of the spot, rather than an explicit intent to hide the art from public view.
Statement 3 is Incorrect: There is no substantial archaeological evidence to suggest that lower walls were reserved for storage, thereby forcing early humans to paint on ceilings. The choice of location is attributed to cultural and spiritual beliefs rather than logistical constraints regarding space utilization.
Key Takeaway: The placement of prehistoric paintings in inaccessible or uncomfortable positions is a strong indicator of their ritualistic function, distinguishing them from everyday domestic activities.
