The book was written by Morice Vanoverbergh, a Belgian Catholic Missionary who worked in the Philippines for decades starting in the 1900s.
After being assigned at a mission in Bauko, Mountain Province in 1909, Vanoverbergh studied, researched, and recorded Igorot culture, traditions, and languages. He wrote several books containing his studies.
