Sweet. Haven't translated it (would have to use google translate and don't know how well that would work) but the pics are cool. Can't remember...have you tried a ribbed vault yet?

This type of dome is widely used in the early Romanesque or Lombard. Is understood as originated by crossing perpendicular two barrel vaults of equal radius find her particularly covering the aisles, and the only ship of small temples, such as San Caprasio in Santa Cruz in the serosa (Huesca).

This type of cover can divide the total length of the ships in smaller sections. And therefore their characteristics when handling his thrusts. But there is another point of great importance in the "mechanism" of this structure: the special design makes the thrust of it is transmitted over existing in each of its four corners pillars. The transcendental consequence is that possible to dispense with the walls of its four sides. This is certainly an important factor in building. Loads a long ship can be fractionated by little "opaque" secondary structures. And to top it off, you open bays in the semicircular spaces generated in height. This will be the base of the lunette, as used in the XVII and XVIII.

It is usual to find the vaults built on rectangular spaces. Four arches require for their development. In the circular tower Fantova (Huesca) arises exception: in the access floor located in altitude, we find a beautiful and well made that needed edge vault wit his Lombard builders (Apo and Guafrido) to "create" the four arches attached to the circular wall of the tower from which flip the vault (upper images).

Over time the vaults are reinforced, or rather embellished with ribs. As is the case with arches, which I call "flashing" the function of the ribs diagonally outlining the edges have no mission that aesthetically enhance the finish of it. Above is an example of this, in the vault of the north transept of Santa Maria in Santa Cruz in the serosa (Huesca).

These vaults are called simple ribbed vaults. And despite their similar etymological root, have no connection with ribbed vaults of their denomination. The ribbed vaults of the different periods and we find in the Romanesque, much later in time when and the Gothic, its ribs and severies campeen atop the temples providing a new and functional aesthetics.
