Antique Manuscript Book of Ritual Knowledge from North Sumatra, 19th century or earlier. Leporello folded book with 26 panels (in addition to the covers) that have writings and drawings on both sides. Each panel is 9cm x 10 cm. About 9 drawings that probably mean something not including the little flowers all over the manuscript. The Pustaha (bark book), were ancient books used by shamans of the Batak tribes of Indonesia. The Pustaha are written in a ritual language that can only be used and understood by the datu, the shaman of the tribe. They record charms, medicine, magic formulae used by the shaman (datu) for cures, rites, amulets, and magic-religious purposes. Condition not perfect.
