Betaljemur Adammlasi is a primbon book by Kangjeng Pangeran Harya (KPH) Tjakraningrat, when he was still active in the Ngayogyakarta Hadiningrat Sultanate, Yogyakarta. This book emerged as a result of the assimilation and acculturation of stories from Islamic treasures, namely the story of Amir Hamzah which in Javanese tradition is called Wong Agung Menak. In the BA primbon book, several aspects of gut science/physiognomy are found in reading people's faces, from the head, hair, forehead/forehead, eyebrows, ears, eyes, nose, mouth, lips, cheeks, teeth, and chin.
