Manuscripts are a very important source to know about our past. They were usually written on the palm leaf or on the bark of a tree, by hand. The palm leaves or the bark of a tree were cut into pages and tied together to make books. These books deal with varied subjects such as, science, medicine, religious beliefs and practices and lives of kings. Besides, there were epics, poems and plays. The language used in the manuscripts was Sanskrit, Prakrit and Tamil.
