Some Heathens seek out common elements found throughout Germanic Europe during the Iron Age and Early Middle Ages, using those as the basis for their contemporary beliefs and practices. Conversely, others draw inspiration from the beliefs and practices of a specific geographical area and chronological period within Germanic Europe, such as Anglo-Saxon England or Viking Age Iceland. Some adherents are deeply knowledgeable as to the specifics of Northern European society in the Iron Age and Early Medieval periods; however for most practitioners their main source of information about the pre-Christian past is fictional literature and popular accounts of Norse mythology. Many express a romanticized view of this past, sometimes perpetuating misconceptions about it; the sociologist of religion Jennifer Snook noting that many practitioners "hearken back to a more epic, anachronistic, and pure age of ancestors and heroes".
