This is a manuscript of Batak tribe ( Indonesia) made of tree bark. The bast of a tree is pulled off in long strips and then prepared and folded like an accordion.
I couldnt understand the content of this manuscript however from the book "Illuminations The writing Traditions of Indonesia" this manuscrit is called pustaha or pustaka. It contains texts on the tribal rituals, oracles & medicine recipes.
Normally this manuscript comes with 2 wooden covers which are missing. This manuscript if unfolded is about 335 cm. Dimension is 25 cm by 18 cm.
This Pustaka was written in Batak script and in this specific manuscript only ones who are trained culd understand the content. According to Van De Tuuk, this text is composed in the language code referred to as Hata Poda.
