ARCADE

(Fr.) In Architecture, a series of arches crowned with a roof or ceiling, with a walk or jja age thereunder. The piers of arcades may be decorated with columns, pilasters, niches, and apertures of different forms. The arches themselves are turned sometimes with rock-worked and sometimes with plain rustic archstones or vou oirs, or with a moulded archivolt, springing from an impost or platband, and sometimes, — though that is not to be recommended, — from columns. The key-stones are generally carved in the form of a console, or sculptured with some device. Seamozzi made the size of his piers le , and varied his imposts and archivolts in proportion to the delicacy of the orders he employed, but Vignola made his piers always of the same proportion.
