Billfrith was an early 8th-century Northumbrian saint and goldsmith who is famously associated with the Lindisfarne Gospels. According to historical records, including a colophon by the scribe Aldred, he created the elaborate metalwork and jewel-encrusted decorations for the original binding of this significant gospel book. Although the original covering did not survive, his craftsmanship was highly regarded, and his name appears in early records such as the Durham Liber Vitae.
