Tamil palm-leaf manuscript
For over two thousand years, scribes have recorded much of India's literary and scientific heritage on the readily available medium of dried, smoothed and smoke-treated leaves of talipot (olai in Tamil) palm trees. Carefully etching letters into the dried leaf with a stylus in a manner that avoids splitting the leaf and later applying lampblack or turmeric to enhance contrast and legibility, uncounted generations of scribes preserved much of India's vast intellectual legacy. When left undisturbed in the tropical climate, these palm-leaf manuscripts could last three or four centuries, after which a new patron would commission scribes to copy the precious manuscripts onto freshly treated palm-leaves.
The existing palm-leaf manuscripts in Tamil on traditional science cover
the following 12 areas:
Given the great intellectual vitality of the Indian mind and Indian
culture's high regard for inherited knowledge, it is no surprise that a
vast corpus of these palm-leaf manuscripts accumulated over the centuries.
Until the appearance of the printing press rendered palm-leaf manuscript
transcription obsolete, Indian rajahs, temple authorities, and other
concerned individuals ensured that the oldest (and hence most valued)
manuscripts were ritually disposed only after they had been copied onto new
- Indigenous medicine, including:
- Ayurveda; and
- Yunani systems
- Human anatomy (Varmam, surgery)
- Veterinary science (Vakatam)
- Agriculture (Kuvam, Karanul)
- Traditional art and architecture:
- Temple art
- Temple architecture
- Traditional musicology
- Techniques of writing
- Astrology & astronomy
- Animal husbandry
- Martial arts
- Physiognomy (Samudria Laksanam)
When this age-old cycle was broken in the 19th century, the remaining
corpus of palm-leaf manuscripts and the knowledge contained in them began a
long slide into obscurity and destruction. With the tradition of the scribe
fast dying and with no new system of recording their contents, not only
have vast quantities of these manuscripts disappeared forever, but even the
very ability to read the archaic palm-leaf script, called Grantha,
today survives only among specially-trained scholars.
A recent tentative survey by the Institute of Asian Studies,
Madras, indicates that there are still about a hundred thousand
palm-leaf manuscripts surviving in South Indian repositories alone, with
thousands more scattered across the subcontinent and overseas. But most of
these palm-leaves are approaching the end of their natural lifetime and are
facing imminent destruction from dampness, fungus, white ants, cockroaches
and - not least of all - disposal by villagers whose actions are dictated
less by reverence than by superstition.
What knowledge is contained in this scattered corpus? A tentative survey
suggests that most are minor or local works of folk literature - a treasure
trove of ethnographic and historical information in itself. But more
practically, some 30-40% of the corpus consists of technical manuals and
works dealing with traditional sciences. These include, notably, tracts
dealing with traditional systems of medicine like Ayurveda, Siddha and
Unani which have been shown to be remarkably effective in the treatment of
a wide variety of diseases.
Hence, the translation and publication of such technical manuals could
potentially yield benefits far outweighing the effort and expense of
recovering them. Many thousands of manuscript-leaves stand to be recovered
- or lost forever - depending upon the action or inaction taken now. The
first stage comprises of identification, collection, conservation
microfilming and preservation of these palm-leaf manuscripts. The second
stage consists of editing translation, textual criticism etc.
The Institute of Asian Studies has assembled a project
team of highly-qualified and dedicated specialists with experience in
preserving and translating palm-leaf manuscripts. Already the project has
published the first five volumes of a projected 25-volume Descriptive
Catalogue of Palm-leaf Manuscripts.
Traditional medical texts
Today there is a growing appreciation worldwide about traditional
knowledge, particularly in the field of medical science. Most Indian
palm-leaf manuscripts on traditional science pertain to medicine such as
the Siddha and Ayurvedic systems of treatment along with the Unani system
popular in the Muslim world. Modern research has demonstrated that these
traditional systems give lasting relief to many chronic diseases. These
systems echew surgery and yet the curing effect is remarkable, even for
very serious diseases which may not cured by allopathic treatment.
Moreover, the native medicines are based either on herbs or metals which
are not injurious to health when used according to traditional
prescription. Nowadays with the help of palm-leaf manuscripts attempts are
being made in India to treat life-threatening diseases like AIDS, heart
disease and diabetes.
The publication of these rare manuscripts will undoubtedly be a welcome
contribution to medical research in India, Asia and worldwide. In India
alone there are a great many medical and technical colleges that will be
eager to access the published results of this project, both in printed and
digital formats. Uncounted humlife improved for millions of others by analysing traditional Asian medical treatments based upon commonly available herbs and minerals.
Being organic in nature, palm-leaf manuscripts are susceptible to decay and
disintegration over time. Most of the extant manuscripts available in the
custodial organisations and with the individual practitioners are on the
verge of disintegration.
Project specialists therefore also take steps to preserve original
Normally chemical treatments are given using fumigation chambers to protect
palm-leaves from white ants, fungus and other insects. Insecticides and
pesticides are useless as the pests develop immunity over time. IAS-trained
specialists treat manuscripts using fumigation boxes or chemicals like
Thymol and chloromate solution.
Digitalization is the crowning stage; the process is currently being
developed by an international team of distinguished scholars from the
University of Cologne (Germany) and the University of California-Berkeley
(USA) with headquarters at the IAS (India) as part of the Tamil Lexicon and
Pongal-2000 collaborative projects to compile an Online Tamil Lexicon
(OTL). This same technology may be applied to digitalize the contents of
palm-leaf manuscripts once they have been rendered into modern Tamil by
specialists in this field.
Once these texts have been translated and digitalized, they will be
disseminated in the form of a searchable online database and as CD-ROMs as
well as conventional publication as books. Libraries around the world
including major manuscript repositories in India will have their own
digital 'reading rooms' where any MS folio may be brought up for viewing.
The pilot programme at the Institute of Asian Studies, Madras, will also
serve as a regional training centre for librarians and manuscriptologists
from other Asian countries that wish to acquire new techniques of
preservation for their national palm-leaf manuscript collections.
