On remarquera que le pignon de Vezelay est un masque de comble
GABLE GABLE (French pignon or pingon, not very used) : from Latin pinna, used since the beginning of the 13th century. Wall located on the small side of a construction, as opposed to the eave wall, generally with a triangle top (case of a two side roof). The gables are made either of brick or stone masonry, or of wood boards, concrete panels or metal boarding. They can either be the frontage, or party walls allowing the backing of flues. In the buildings covered with a flat roof, the gables are square or rectangular. The historical evolution of the gable reveals major changes in its destination and its treatment. Greek and Roman architects reserved the gable to the principal frontage of the temples such as for example the pediment of the Parthenon (1). At the Roman time, the gables were decorated with overlapping ornaments, sometimes carved with incrustations of coloured elements. The gates of an gothic cathedral transept are integrated into gable walls (2). "On remarquera que le pignon de Vezelay est un masque de comble, mais ne se combine guère avec sa forme. Dans nos édifices gothiques du XIIIe siècle, ceux de l'île de France, ceux auxquels il faut toujours recourir comme étant l'expression classique de cet art, les pignons sont bien faits pour fermer le comble, ils s'éclairent franchement et le recouvrent." Viollet-Le-Duc, Dictionnaire Raisonné de l'Architecture Française. In civil architecture up to the Renaissance, the row houses very often have their gable along the street, hence the French expression "avoir pignon sur rue (to have gable onto the street)". Made of timber frames in northern, eastern and central France, they have then very marked corbellings at their corner (4). In Flemish countries and Hanseatic cities, the gables have various shapes in particular the crowstepped gable (5) and bright colours like in the town of Gdansk, in Poland (6). The baroque time will cover them with trompel'œil frescos and will give them a circumvented silhouette. The Hausmann architecture reduces the gable to a function of party walls integrating or supporting the flues while others are dedicated to a monumental decoration like the SaintMichel fountain in Paris (3). After the excesses of advertising murals at the end of the 19th century (7), the modern movement refined the gable by giving it a double function, either as a screen or an open frontage; we are given the most famous examples by Corbusier in its Radiant City of Marseilles or the dwelling unit (unité d'habitation) in Firminy (8), where the NorthSouth orientation plays an essential part, the South being reserved for a frontage open to the dwellings, the North having a blind gable in the shade. Then thanks to the 1% of public construction cost devoted to the visual arts, the gables have been covered with figures as for example the ornamental ceramics panels and the murals in Chanteloup-lesVignes (9) ; Sometimes, only one well placed ornament is enough to give character to a wall. More modestly but in an expressive way, some villages use the gable as a defence against the climatic Planche extraite du " Vocabulaire illustré de l'Art urbain ".R.-M. A./C. L. Avril 2001/A.V. Juillet 2001 rigours, with a great plastic value (10). Such are the sets of Breton houses with granite gables incorporating the flue; nearer to us, one finds them in the mining cities or the south of France, made of bricks and treated with much elegance (A, B, C, D). The creation of angular buildings removes the gable in modern architecture, and affirms the autonomy of the building and the bursting of the urban composition; however, the case of tower CBX in la Défense (11) , , brings us back to the treatment of the angle of two streets and takes as a starting point the New York "Flat Iron", to make a plastic effect in an urban window. * Thus, the gable walls have as much importance as the other frontages in the architectural design. They can be "art in the street" and be the subject of a plastic treatment in the urban composition. . Cf.
