Children of Godan III: Heathen Langobard Nation
Heathen means "not Christian," similar to the word infidel in it's usage. Paul the Deacon, an extremely dedicated servant of the Roman Church, when composing his work 'History of the Lombards, seemed clearly to view the pagan beliefs and mythology of the Lombards as something to be frowned upon. However, in other areas, I think that Edward Peters wasn't entirely fair in some of his contradictions of Paul the Deacon.
After migrating to Pannonia, some of the Lombards converted to something called Arian Christianity. Later in their Langbard Kingdom, Queen Theodelinda brought the Roman Church into the kingdom, and the old ways eventually disappeared. However, their pagan ways lasted many centuries, and ultimately went back thousands of years. Some say as long as forty thousand years.
