Purbawidya is a journal that publishes research, conceptions, and ideas on the development of archaeology. This paper explores the meaning and significance of “Purbawidya”, which translates to “Past Knowledge” in English. Using various approaches from archaeology, anthropology, sociology, philology, history, architecture, geography, geology, biology, chemistry, ecology, and other sciences, this paper analyses how humans and past cultures are studied and understood through Purbawidya. The paper argues that Purbawidya is not only a journal name, but also a concept that reflects the interdisciplinary and holistic nature of archaeological inquiry.
