FORM, in carpentry, is used to denote the long seats or benches in the choirs of churches or in schools, for the priests, prebends, religious persons, or scholars, to sit on. Du Cange supposes the name to be derived from this, that the backs of the seats were anciently enriched with figures of painting and sculpture, called in Latin formæ et typi. In the life of St William of Roschild, we meet with forma as signifying a seat for an ecclesiastic, or religious person, in a choir; and in that of St Lupicin, we find formula used in the same sense. In the rule of the monastery of St Cesarea, the man who presides over the choir is called the occupant of the first form or seat.
