The interior of the Cathedral is very large and lofty. It is without aisles and the chapels are discreetly hidden between the piers. Far above one's head curves the ribbed Gothic vaulting, and all around is unbroken space that ends in darkness or the vague outline of an altar, dimly lighted by a flickering candle. The walls are painted in rich, sombre colours, and the light comes very gently through the good old stained-glass windows. It is a southern church, dark, cool, and somewhat mysterious; quite foreign to the glare and heat of reality. People are lost in its solemn vastness, and even with many worshippers it is a solitude where most holy vigils could be kept, a mystic place where the southern imagination might well lose itself in such sacred ardours as Saint Theresa felt. The traveller liked to linger here; in the day-time when he peered vainly at the re-redos of Soler de Barcelona, at Mass-time, when the lighted altar-candles glimmered over its fine old marble, but best of all he liked to come at night. Those summer nights in Rousillon were hot and full of the murmur of voices. The Cathedral was the only silent place; more full than ever of the mysterious--the felt and the unseen. As one entered, the sanctuary light shone as a star out of a night of darkness; in a near-by chapel, a candle sputtered itself away, and a woman--whether old or young one could not see--lighted a fresh taper. Sometimes a man knelt and told his beads, sometimes two women entered and separated for their differing needs and prayers. Sometimes one sat in meditation, or knelt, unmoving, for a space of time; once a child brought a new candle to Saint Antony; always some one came or some one went, until the hour of closing. Then, the bell was rung, the door shut by a hand but dimly seen, and the last few watchers went out--across the little square, down this street or that, until they were lost in the darkness of the summer's night.
