TAMBOUR, in Architecture, a term applied to the Corinthian and Composite capitals, as bearing some resemblance to a drum, which the French call tambour. Some choose to call it the vase, and others campana or the bell.
TAMBOUR is also used for a little box of timber work, covered with a ceiling, within the porch of certain churches; both to prevent the view of persons passing by, and to keep off the wind, &c. by means of folding-doors, &c.
