Support change
In architecture, a column change is the rhythmic alternation of thick and slim pillars and / or columns . It was common in the nave of flat-roofed pre-Romanesque basilicas . In the quadratic scheme , especially in the bound system , the change of supports emphasizes the geometric structure and often also the supporting structure of the building .
to form
When changing pillars in the Rhineland , pillar and column followed one another alternately; when changing (Lower) Saxon columns , two columns were placed on each pillar. When changing pillars in Lower Saxony, there are inevitably two freestanding pillars and six pillars on each side (i.e. four or twelve in total) with three longship bays, which was of numerical significance. (4 evangelists, 12 apostles)
When the groin vault was introduced , it became customary to place half-columns ( services ) in front of the pillars - statically not absolutely necessary - that reached as far as the warriors of the vault. In return, the pillars in between were replaced by mostly simple pillars (e.g. Worms Cathedral ), so that a rhythmic arrangement was retained. In the Gothic period , with a few exceptions, changing pillars was finally abandoned.
