Sources and style

Figurative sculpture was based on two other sources in particular, manuscript illumination and small-scale sculpture in ivory and metal. The extensive friezes sculpted on Armenian and Syriac churches have been proposed as another likely influence. These sources together produced a distinct style which can be recognised across Europe, although the most spectacular sculptural projects are concentrated in South-Western France, Northern Spain and Italy.

Images that occurred in metalwork were frequently embossed. The resultant surface had two main planes and details that were usually incised. This treatment was adapted to stone carving and is seen particularly in the tympanum above the portal, where the imagery of Christ in Majesty with the symbols of the Four Evangelists is drawn directly from the gilt covers of medieval Gospel Books. This style of doorway occurs in many places and continued into the Gothic period. A rare survival in England is that of the "Prior's Door" at Ely Cathedral. In South- Western France, many have survived, with impressive examples at Saint-Pierre, Moissac, Souillac, and La Madeleine, Vézelay – all daughter houses of Cluny, with extensive other sculpture remaining in cloisters and other buildings. Nearby, Autun Cathedral has a Last Judgement of great rarity in that it has uniquely been signed by its creator, Giselbertus.

A feature of the figures in manuscript illumination is that they often occupy confined spaces and are contorted to fit. The custom of artists to make the figure fit the available space lent itself to a facility in designing figures to ornament door posts and lintels and other such architectural surfaces. The robes of painted figures were commonly treated in a flat and decorative style that bore little resemblance to the weight and fall of actual cloth. This feature was also adapted for sculpture. Among the many examples that exist, one of the finest is the figure of the Prophet Jeremiah from the pillar of the portal of the Abbey of Saint-Pierre, Moissac, France, from about 1130.

One of the most significant motifs of Romanesque design, occurring in both figurative and non-figurative sculpture is the spiral. One of the sources may be Ionic capitals. Scrolling vines were a common motif of both Byzantine and Roman design, and may be seen in mosaic on the vaults of the 4th century Church of Santa Costanza, Rome. Manuscripts and architectural carvings of the 12th century have very similar scrolling vine motifs.

Another source of the spiral is clearly the illuminated manuscripts of the 7th to 9th centuries, particularly Irish manuscripts such as the St. Gall Gospel Book, spread into Europe by the Hiberno-Scottish mission. In these illuminations the use of the spiral has nothing to do with vines or other plant forms. The motif is abstract and mathematical. The style was then picked up in Carolingian art and given a more botanical character. It is in an adaptation of this form that the spiral occurs in the draperies of both sculpture and stained glass windows. Of all the many examples that occur on Romanesque portals, one of the most outstanding is that of the central figure of Christ at La Madeleine, Vezelay.

Another influence from Insular art are engaged and entwined animals, often used to superb effect in capitals (as at Silos) and sometimes on a column itself (as at Moissac). Much of the treatment of paired, confronted and entwined animals in Romanesque decoration has similar Insular origins, as do animals whose bodies tail into purely decorative shapes. (Despite the adoption of Hiberno-Saxon traditions into Romanesque styles in England and on the continent, the influence was primarily one-way. Irish art during this period remained isolated, developing a unique amalgam of native Irish and Viking styles which would be slowly extinguished and replaced by mainstream Romanesque style in the early 13th century following the Anglo-Norman invasion of Ireland.)
