Hubertus was a Frankish bishop who lived during the late 7th and early 8th centuries. Born in Toulouse to a noble family, he initially served at royal courts before undergoing a spiritual transformation. Following the death of his wife, he sought solitude in the Ardennes forests. He is famously remembered for a vision involving a stag with a crucifix between its antlers, an event that led him to renounce his worldly status. He eventually served as the bishop of Maastricht and became the first bishop of Liège.
