Ancient Sanskrit manuscript goes digital

Scientists from the US are using modern imaging techniques to digitally

restore a rare 700-year-old Indian palm leaf manuscript on Hinduism.

 

Restorers from New York's Rochester Institute of Technology (RIT) are

working on Sarvamoola Grantha which expounds on the essence of Hindu

philosophy, the meaning of life and the role of God.

 

This priceless collection of 36 erudite commentaries was written in Sanskrit

by Sri Madvacharya (1238-1317 AD), one of India's greatest theologians.

 

In addition to commentaries based on sacred Hindu scriptures such as the

Vedas, Upanishads, Gita, Puranas, Brahma-sutras, Mahabharata and others, the

collection also includes independent philosophical tracts, a commentary on

daily rites, and several hymns in praise of God.

 

Dr PR Mukund, a professor of electrical engineering at RIT, is leading the

project along with his colleague Roger Easton.

 

"Among the various scholars and spiritual leaders in India during the last

millennium, Sri Madvacharya had a profound impact on the society," explains

Dr Mukund.

 

"He analysed all aspects of Hindu holy texts and showed the structure of the

spiritual world that serves as a backbone of the world's diversities. As a

result, preservation of this collection for future generations is

essential," he says.

 

Deteriorating

These manuscripts were stored at Phalimaru Matha (a monastic establishment

of the Hindu tradition) near the coastal town of Udupi in the southern

Indian state of Karnataka.

 

Dr Mukund has had a long association with several such mathas and has been

actively involved in the publication of books on philosophy.

 

The badly damaged leaves of the manuscript must first be organised

He was unnerved by the deteriorating condition of the 13th century

manuscripts.

 

"Over time, many of the original manuscripts were lost or were badly damaged

due to deterioration of the palm leaves," he reveals.

 

Many leaves are cracked or have chipped off. Substantial parts of the leaves

are missing in some collections. Friction between the binding cord and the

edge of the hole on the palm leaves has further damaged them.

 

Inappropriate storage has led to the palm leaves staining, splitting and

sticking to each other. As a result, the manuscript is very brittle and

difficult to handle without further damage.

 

"The palm leaves have darkened over time and are now dark brown in colour,"

adds Dr Mukund. This has made it difficult to read the manuscript with the

naked eye.

 

Cutting edge

The project is making use of cutting-edge technology to digitally restore

the manuscripts.

 

We have started the project, but have no money to pay staff and lab fees

Initially, high-resolution images of the manuscripts are acquired.

 

Depending upon the size and format of the manuscript, each leaf can be

captured in five or more sections.

 

These sections are then connected to make an image of the complete palm

leaf. After this, the images are processed to enhance the readability of the

text.

 

The team is also preparing to use a novel long-term storage technique.

 

For the first time, images of the palm leaves will be etched on the silicon

wafers normally used in the microelectronic industry.

 

Dr Mukund explains that silicon wafers can withstand very high temperatures

and are not affected by the presence of water. It will also be possible to

read these images without using additional equipment.

 

The team also plans to image some 800 more palm leaf manuscripts written

since the time of Sri Madvacharya.

 

However, all of this would need substantial funds.

 

"We need about $100,000 per year for the next three years," Dr Mukund says.

"We have started the project, but have no money to pay staff and lab fees

for silicon processing."
