Researchers attempt to stay within research guidelines developed over the course of the past century for handling documentation generated in the time periods that they are studying. A multi-disciplinary approach is utilized capitalizing on results from various fields as historical literary research, anthropology, religious history, political history, archaeology, forensic anthropology, historical sociology, etc. with an overt attempt to avoid pseudo-sciences. There are serious attempts to recreate culture, politics, science and art of the period in order to better understand the environment within which the religious beliefs were practiced.[5]
