About two hundred years later, in 1285, the Archbishop of Aix found the Cathedral too unpretending for the rank and dignity of the See, and he began the Gothic additions. Like many another prelate his ambitions were larger than his means; and the history of Saint-Sauveur from the XIII to the XIX century, is that oft-told tale of new indulgences offered for new contributions, halts and delays in construction, emptied treasuries, and again, appeals and fresh efforts. The beginnings of the enlarged Cathedral were architecturally abrupt. The old nave, becoming the south aisle, was connected with the new by two small openings; it retained much of its separateness and in spite of added chapels much actual isolation. The Gothic nave, the north aisle and its many chapels, the apse, and the transepts, whose building and re-construction stretched over the long period between the XIII and XVII centuries, are comparatively regular, uniform, and uninteresting. The most ambitious view is that of the central nave, whose whole length is so little broken by entrances to the side aisles, that it seems almost solidly enclosed by its massive walls. Here in Gothic bays, are found those rounded, longitudinal arches which belong to the Romanesque and to some structure whose identity is buried in the mysterious past. The choir, with its long, narrow windows, and clusters of columnettes, is very pleasing, and its seven sides, foreign to Provence, remind one of Italian and Spanish constructive forms and take one's memory on strange jaunts, to the far-away Frari in Venice and the colder Abbey of London. From the choir of Saint-Sauveur two chapels open; and one of them is a charming bit of architecture, a replica in miniature of the mother-apse itself. The paintings of this mother-apse are neutral, its glass has no claim to sumptuousness, and the stalls are very unpretending; but above them hang tapestries ascribed to Matsys, splendid hangings of the Flemish school that were once in old Saint Paul's.
