 Chevrons and other geometric ornaments, referred to by 19th-century writers as "barbaric ornament", are most frequently found on the mouldings of the central door.Stylized foliage often appears, sometimes deeply carved and curling outward after the manner of the acanthus leaves on Corinthian capitals, but also carved in shallow relief and spiral patterns, imitating the intricacies of manuscript illuminations.In general, the style of ornament was more classical in Italy, such as that seen around the door of San Giusto in Lucca, and more "barbaric" in England, Germany and Scandinavia, such as that seen at Lincoln and Speyer Cathedrals.
