In the last years of the twelfth-century, a monk named Engelhard, from the German monastery of Langheim, composed stories about miraculous events and visions he believed his fellow monks had experienced. This was not a decision made lightly: parchment was expensive, the process of writing laborious, and monastic authors needed permission from their superiors to write at all. But Engelhard (and his abbot) considered this project worthwhile.
