_Dax_ At Dax, an ancient thermal station of the Romans, is a small cathedral, mainly modern, with a portal of the thirteenth century. It was reconstructed from these thirteenth-century remains in the seventeenth century, and exhibits no marks of beauty which would have established its ranking greatness even at that time. Dax was a bishopric in the province of Auch in the third century, but the see was suppressed in 1802. _Eauze_ Eauze was an archbishopric in the third century, when St. Paterne was its first dignitary. Subsequently--in the following century--the archbishopric was transferred to Auch. As _Elusa_ it was an important place in the time of Cæsar, but was completely destroyed in the early part of the tenth century. Eauze, therefore, has no church edifice which ever ranked as a cathedral, but there is a fine Gothic church of the late fifteenth century which is, in every way, an architectural monument worthy of remark. _Lombez_ The bishopric of Lombez, in the ancient ecclesiastical province of Toulouse, endured from 1328 (a tenth-century Benedictine abbey foundation). Its first bishop was one Roger de Comminges, a monk who came from the monastic community of St. Bertrand de Comminges. The see was suppressed in 1790. _St. Papoul_ St. Papoul was a bishopric from 1317 until 1790. Its cathedral is in many respects a really fine work. It was an ancient abbatial church in the Romanesque style, and has an attractive cloister built after the same manner. _Rieux_ Rieux is perhaps the tiniest _ville_ of France which has ever possessed episcopal dignity. It is situated on a mere rivulet--a branch of the Arize, which itself is not much more, but which in turn goes to swell the flood of La Garonne. Its one-time cathedral is perhaps not remarkable in any way, though it has a fine fifteenth-century tower in _brique_. The bishopric was founded in 1370 under Guillaumé de Brutia, and was suppressed in 1790. _Lavaur_ Lavaur was a bishopric, in the ecclesiastical province of Toulouse, from 1317 to 1790. Its cathedral of brick is of the fourteenth century, with a _clocher_ dating from 1515, and a smaller tower, embracing a _jacquemart_, of the sixteenth century. In the interior is a fine sixteenth-century painting, but there are no other artistic treasures or details of note. _Oloron_ Oloron was a bishopric under St. Gratus in the sixth century; it ceased its functions as the head of a diocese at the suppression of 1790. The former cathedral of Ste. Marie is a fine Romanic-Ogivale edifice of the eleventh century, though its constructive era may be said to extend well toward the fifteenth before it reached completion. There is a remarkably beautiful Romanesque sculptured portal. The nave is doubled, as to its aisles, and is one hundred and fifty feet or more in length and one hundred and six wide, an astonishing breadth when one comes to think of it, and a dimension which is not equalled by any minor cathedral.
