Compound piers with nook shafts in Lombard Romanesque churches receive transverse arches always by pilasters and not by round shafts. The composition differs essentially from that of compound piers with nook shafts in Ile-de-France. Detailed measurements of the supports in eleven Lombard churches indicate the following.<br>1) Nook shafts in Lombard compound piers penetrate the re-entrant corner of <i>ressauts</i> to the extent that about half of the circular profile is hidden. This feature means that Lombard compound piers have low linearity compared to that of Ile-de-France compound piers in which nook shafts touch both the surfaces of the re-entrant corner tangentially.<br>2) However, the nook shaft in Lombardy has "diagonality" because it penetrates each of the two surfaces of the re-entrant corner to the same extent. Accordingly, the theory of "diagonality," by which Paul Frankl asserts this to be a key characteristic of Gothic architecture, fails as far as Lombard architecture is concerned.
