Gothic Capitals use the same ductus as the minuscules and are written with the same “slanted” pen. However the capitals have a wider, rounder aspect than the rigidly formal minuscules, and the two forms contrast strikingly when used together. The number of calligraphy flourishes in each Gothic Capital make it an unsuitable script for writing a whole word or a full page of text. For this, Lombardic Capitals provide a less flamboyant alternative.
