Fragmentary records indicate that Fulke's origins were in Flanders during a time of political upheaval and Viking raids. She is an enigmatic figure who more fully emerges in the historical record in England where she appears as a mixture of gnostic mystic and paladin.
Any young Flemish woman would aspire to that combination: paladin by day, gnostic mystic when evening falls.
She proved to be a thorn in the side of both the religious and secular authorities of the day. Records of her work in England exist largely due to surviving references in the journal entries of a defrocked priest known only as Paul.
