Palm-leaf manuscripts are manuscripts made out of dried palm leaves. Palm leaves were used as writing materials in the Indian subcontinent and in Southeast Asia dating back to the 5th century BCE and possibly much earlier. Their use began in South Asia and spread elsewhere, as texts on dried and smoke treated palm leaves of Borassus species (Palmyra palm) or the Ola leaf (leaf of Corypha umbraculifera or the talipot palm).
Palm leaf manuscripts were written in ink on rectangular cut and cured palm leaf sheet. Each sheet typically had a hole through which a string could pass through, and with these the sheets were tied together with a string to bind like a book. A palm leaf text thus created would typically last between a few decades and about 600 years before it decayed due to dampness, insect activity, mold and fragility. Thus the document had to be copied onto new sets of dried palm leaves. The oldest surviving palm leaf Indian manuscripts have been found in colder, drier climates such as in parts of Nepal, Tibet and central Asia, the source of 1st-millennium CE manuscripts.
The individual sheets of palm leaves were called Patra or Parna in Sanskrit (Pali/Prakrit: Panna), and the medium when ready to write was called Tada-patra (or Tala-patra, Tali, Tadi). The famous 5th-century CE Indian manuscript called the Bower Manuscript discovered in Chinese Turkestan, was written on birch-bark sheets shaped in the form of treated palm leaves.
Hindu temples often served as centers where ancient manuscripts were routinely used for learning and where the texts were copied when they wore out. In South India, temples and associated mutts served custodial functions, and a large number of manuscripts on Hindu philosophy, poetry, grammar and other subjects were written, multiplied and preserved inside the temples. Archaeological and epigraphical evidence indicates existence of libraries called Sarasvati-bhandara, dated possibly to early 12th-century and employing librarians, attached to Hindu temples. Palm leaf manuscripts were also preserved inside Jain temples and in Buddhist monasteries.
With the spread of Indian culture to Southeast Asian countries like as Indonesia, Cambodia, Thailand, and the Philippines, these nations also became home to large collections. Palm-leaf manuscripts called Lontar in dedicated stone libraries have been discovered by archaeologists at Hindu temples in Bali Indonesia and in 10th century Cambodian temples such as Angkor Wat and Banteay Srei.
One of the oldest surviving Sanskrit manuscripts on palm leaves is of the Parameshvaratantra, a Shaiva Siddhanta text of Hinduism. It is from the 9th-century, and dated to about 828 CE. The discovered palm-leaf collection also includes a few parts of another text, the Jñānārṇavamahātantra and currently held by the University of Cambridge.
With the introduction of printing presses in the early 19th century, the cycle of copying from palm leaves mostly came to an end. Many governments are making efforts to preserve what is left of their palm leaf documents.
The round and cursive design of the letters of many South Indian and Southeast Asian scripts, such as Devanagari, Nandinagari, Telugu, Lontara, Javanese, Balinese, Odia, Burmese, Tamil, Khmer, and so forth, may be am adaptations to the palm leaves, because angular letters may tear the leaves apart.
Palm leaf manuscripts of Odisha include scriptures, pictures of Devadasi and various mudras of the Kama Sutra. Some of the early discoveries of Odia palm leaf manuscripts include writings like Smaradipika, Ratimanjari, Pancasayaka and Anangaranga in both Odia and Sanskrit. State Museum of Odisha at Bhubaneswar houses 40,000 palm leaf manuscripts.Most of them are written in the Odia script, though the language is Sanskrit. The oldest manuscript here belongs to the 14th century but the text can be dated to the 2nd century.
In 1997 The United Nations Educational Scientific and Cultural Organisation (UNESCO) recognised the Tamil Medical Manuscript Collection as part of the Memory of the World Register. A very good example of usage of palm leaf manuscripts to store the history is a Tamil grammar book named Tolkāppiyam which was written around 3rd century BCE. A global digitalization project led by the Tamil Heritage Foundation collects, preserves, digitizes and makes ancient palm-leaf manuscript documents available to users via the internet.
In Indonesia the palm-leaf manuscript is called lontar. The Indonesian word is the modern form of Old Javanese rontal. It is composed of two Old Javanese words, namely ron "leaf" and tal "Borassus flabellifer, palmyra palm". Due to the shape of the palmyra palm's leaves, which are spread like a fan, these trees are also known as "fan trees". The leaves of the rontal tree have always been used for many purposes, such as for the making of plaited mats, palm sugar wrappers, water scoops, ornaments, ritual tools, and writing material. Today, the art of writing in rontal still survives in Bali, performed by Balinese Brahmin as a sacred duty to rewrite Hindu texts.
Many old manuscripts dated from ancient Java, Indonesia, were written on rontal palm-leaf manuscripts. Manuscripts dated from the 14th to 15th century during the Majapahit period. Some were found even earlier, like the Arjunawiwaha, the Smaradahana, the Nagarakretagama and the Kakawin Sutasoma, which were discovered on the neighboring islands of Bali and Lombok. This suggested that the tradition of preserving, copying and rewriting palm-leaf manuscripts continued for centuries. Other palm-leaf manuscripts include Sundanese language works: the Carita Parahyangan, the Sanghyang siksakanda ng karesian and the Bujangga Manik.
The palm leaves are first cooked and dried. The writer then uses a knife pen to inscribe letters. Natural colourings are applied to the surface so the ink will stick in the grooves. This process is similar to intaglio printing. Afterwards, a clean cloth is used to wipe out the excess ink and the leaf manuscript is done.
