Saint Lycerius was a 6th-century bishop of Couserans who lived during the late fifth and early sixth centuries. Born in the Iberian Peninsula, he was later associated with the region of Tarbes, where he studied under local clergy before being ordained a priest. He is historically noted for his participation in the Council of Agde in 506. During his tenure, he also managed the diocese of Tarbes while it remained vacant. He is remembered as a holy figure who is credited with performing various healing miracles.
Life and service
According to tradition, Lycerius was a native of Civitas Bigorra. After his priestly ordination by the bishop of Rodez, his reputation for sanctity led to his election as bishop. He served the Couserans diocese and also administered the vacant see of Tarbes for several decades, specifically from 506 until 541.
Veneration and legacy
Following his death in 548, he was interred in the site that is now Saint-Lizier Cathedral. He serves as the patron of several locations in southwestern France, including Saint-Lizier, Saint-Lizier d'Ustou, and Saint-Lizier-du-Planté. In Catalonia, he is linked to Lleida, where he is a secondary patron. His feast day is observed on 27 August.
