Batak priests (datu) inscribed sacred texts on sheets of bark, bamboo cylinders, and the rib bones of water buffalo. These writings-magic formulas, oracles, recipes for medicines, and instructions for rituals and cures-were passed from generation to generation within a priestly class. Inscriptions on rib bones often contain calendrical information used by priests to divine auspicious days for particular activities. The bones also brought good luck to their owners. The beauty of the script and the poetic language were both appreciated.
