Briefings

Recent research using X-rays and machine learning has identified material signatures in palm-leaf manuscripts from South and Southeast Asia, revealing that leaves underwent extensive preparation before inscription. This study provides the first evidence of distinct material signatures left by ancient processing techniques, offering a new method to trace the origins of these historical texts.

Key points

• X-ray imaging and machine learning successfully identified material signatures in palm-leaf manuscripts from South and Southeast Asia.
• Processing techniques varied across regions, potentially leaving distinct material signatures that can now be analyzed.

Context and limitations

The study relies on limited X-ray data and machine learning models; results are preliminary and subject to further validation.
