In its general plan it is of generous though not majestic proportions, and is rich and aspiring in its details throughout.
An ancient altar in this present church is supposed to have come from the humble basilica which was erected here by St. Taurin, bishop of Eauze, soon after the foundation of the see. If this is so, it is certainly of great antiquity, and is exceedingly valuable as the record of an art expression of that early day.
Taurin II., in 845, rebuilt a former church, which stood on the site of the present cathedral; but, its dimensions not proving great enough for the needs of the congregation, St. Austinde, in 1048, built a much larger church, which was consecrated early in the twelfth century.
Various other structures were undertaken, some completed only in part and others to the full; but it was not until 1548 that the present Ste. Marie was actually consecrated by Jean Dumas.
"This gorgeous ceremony," says the Abbé Bourassé, "was accomplished amid great pomp on the anniversary day of the dedication of the eleventh-century basilica on the same site."
In 1597 further additions were made to the vaulting, and the fine choir glass added. Soon after this time, the glass of the nave chapels was put into place, being the gift of Dominique de Vic. The final building operations—as might be expected—show just the least suspicion of debasement. This quality is to be remarked in the choir-screen, the porch and towers, and in the balustrades of the chapels, to say nothing of the organ supports.
The west front is, in part, as late as the seventeenth century.
In this façade there is an elaborately traceried rose window, indicating in its painted glass a "Glory of Angels." It is not a great work, as these chief decorative features of French mediæval architecture go, but is highly ornate by reason of its florid tracery, and dates, moreover, from that period when the really great accomplishment of designing in painted glass was approaching its maturity.
If any feature of remark exists to excite undue criticism, it is that of a certain incongruity or mixture of style, which, while not widely separated in point of time, has great variation as to excellence.
