Roman Catholic Archdiocese of Eauze

The former Roman Catholic Metropolitan Archdiocese of Eauze (Latin Elusa), in Aquitaine, south-west France, existed from circa 300 to 879.

The present Eauze Cathedral, dedicated to St. Luperculus, was built around 500 and became co-cathedral of the successor see Archdiocese of Auch in 1864.

Elusa, capital of the Gallic Late Roman province of Novempopulania since Emperor Diocletian split if off from Gallia Aquitania, was also made its Metropolitan Archbishopric, plausibly soon after.

The first historical mention of an (anonymous) bishop of Eauze is at the Council of Arles (314).

His four alleged successors (Saint Servandus, Saint Optatus, Saint Pompidianus and Taurinus) are only known from an AD 1106 document from the church of Auch (its successor), which claims the last transferred the see to Auch after the Vandals would have wrecked the city and ignores the later Metropolitans (except perhaps confounding Taurinus).
