Perspective portals of 13th century Silesian churches

    Perspective portals are portals with widely splayed jambs, which could be formed in various ways. In up-to-date estimations of these portals sculptured forms played the most important role, architectonic forms were less important. An analysis of the architectonic shaping of the portals carried out by the author, and especially their horizontal cross-sections, allowed presenting their development throughout the 13th century.
    An offset portal with small columns of a large diameter was the initial form at the beginning of the century. New elements appeared around 1230, endowing the portals with early-Gothic features. More and more varied moulding of the jambs, using convex and concave forms, before the end of the 13th century led to the emergence of perspective portals of two arrangements. One of them was a continuation of the offset portal development, with columns. The other was a new portal arrangement in which the offset form disappeared – the jambs were created by several elements standing along an outspreading line, placed on a common plinth of a diagonal line and joined by a common moulding.
