The paintings of Pala school of art were generally executed on palm leaf. The Pala dynasty ruled over the eastern part of the Indian subcontinent from the 8th to the 12th century CE. The Pala school of art is famous for its exquisite paintings, sculptures, and metal works.

Palm leaf manuscripts were a popular medium for writing and painting during the Pala period. The palm leaves were dried and treated with natural preservatives before use. The artists then used a sharp stylus to etch the outlines of the figures and motifs on the leaf. They then filled in the details using natural pigments made from plants and minerals.

The paintings of the Pala school of art were executed on palm leaf in a variety of styles, including:

1. Miniature Paintings: These were small, highly detailed paintings that depicted religious and mythological themes. They were often used as illustrations in religious texts.

2. Narrative Paintings: These were larger paintings that told stories from the Mahabharata, Ramayana, and other religious texts. They were painted in a sequential manner, with each panel depicting a different scene from the story.

3. Iconographic Paintings: These paintings depicted deities and their various attributes. They were used for meditation and worship.

Overall, the paintings of the Pala school of art executed on palm leaf are considered to be some of the finest examples of Indian art. Their intricate details and vibrant colors continue to inspire artists and art lovers even today.
