The correct option is Wooden covers used to bind and protect the folios.
Explanation
Ancient Indian manuscripts, particularly those inscribed on palm leaves (Tadpatra) or birch bark (Bhojpatra), were preserved in a format known as the Pothi style. Due to the fragile nature of the leaves, a sturdy external covering was required for protection.Detailed Analysis:
- The term 'Patlis' (or Patli) refers to the pair of wooden strips or planks used as covers to sandwich the stack of manuscript folios.
- These wooden covers protected the leaves from physical damage, curling, and external elements.
- The manuscript bundle was typically bound by passing a cord through a hole in the center of the leaves and the wooden covers.
- In the history of Indian art, particularly in the Pala School (Eastern India) and the Western Indian School (Jain style), these Patlis were often elaborately painted with religious themes, serving as some of the earliest examples of miniature painting on wood.
Key Takeaway:
Patlis are the protective wooden book covers used in the traditional Pothi format of Indian manuscripts, often serving as a medium for miniature art.
