Tibet.- Perfection of Wisdom in a Hundred Thousand Lines, manuscript in Tibetan, on paper, c.209 leaves, lacks 7 leaves (1-3, 84-87), text in silver-coloured ink to recto and verso, on a black background, border treated with arsenic solution to prevent insect damage, text area polished with rice powder to stabilise ink, paper quite fragile with occasional chipping or fraying to edges, one leaf with more substantial loss (half remaining), occasional small insect damage or loss, leaves loose, housed in a modern cloth drop-back box, each leaf c.150 x 495mm., [Western Tibet, Ladakh], [15th-16th century]. *** Contains four chapters (62-64) of the multi-volume Satasahasrika Prainaparamita, belonging to the genre of Perfection of Wisdom texts composed sometime between 100 and 300 AD. Central to Mahayana Buddhist philosophy, the text was routinely broken up into smaller, more manageable parts for travel and in-depth study. Paper-flaws imply that the manuscript was prepared in a local setting, with high-quality paper in limited supply.
