In the Collegiata of Sta. Ana, we have the next stage in the development of Catalan architecture. This is said to have been built in A.D. 1146,[281] and is also a cruciform church, with a central raised lantern, barrel vaults in the transepts, and two bays of quadripartite vaulting in the nave. The nave probably dates from about the end of the twelfth or beginning of the thirteenth century, being lighted with simple lancet-windows, and having bold buttresses. When I visited this church the chancel was boarded up for repairs, and I am unable to say certainly whether the east end is old, but it appeared to me to have been modernized. The exterior of the lantern is very peculiar; above the roof it is square in plan, but with eight buttresses around it, radiating from the centre, and evidently intended to be carried up so as to form the angles of an octagonal central lantern, of which, however, only the lowest stage remains. The present finish of the lantern is a steep tiled roof, which springs from just above the point at which the angles of the square base are cut off; and on the western slope of this roof a steep flight of stone steps leads to the very summit. The object of this arrangement is quite unintelligible. At the west end of the church, and set curiously askew to it, is a cloister of the fourteenth century, with a Chapter-room on its east side, opening to the cloister with a round-arched doorway, on either side of which is a good early middle-pointed two-light window, making the group so invariably found in old Chapter-house entrances. The west doorway of the church is severely simple, with a square opening and plain tympanum, under a pointed arch. Along the north side of the cloister is a fine ruin of a hall of the thirteenth century, the construction of which is very characteristic and peculiar. It is of two stages in height. Segmental arches across the lower rooms carry the floor beams, which are placed longitudinally, and over them in the upper room bold pointed arches are thrown to carry the roof. The roof was of very flat pitch, and consisted of a series of purlines resting on corbels built into the wall over the stone arches, upon which were laid the common rafters. I shall have to illustrate a similar roof which still remains in the church of Sta. Agata, so that I need not say more on the subject now than that this type is an exceedingly effective one, and occurs repeatedly in the Barcelonese buildings. The cloister of Sta. Ana is of two stages in height, and very light, graceful, and Spanish in its character. The columns are quatrefoil in section, and the capitals are later works of the same eastern character as those already described in San Pedro, and have square abaci. There is, perhaps, scarcely sufficient appearance of solidity and permanence in such extremely light shafts, seeing that they have to support a double tier of arcades all round the cloister; but nevertheless the whole effect of the work is very beautiful.
