The earliest stallwork of which we have remains is in Rochester cathedral (30). From fragments which remained it was found that the stalls had been about 3 feet 6 inches high, and had hinged seats only 13½ inches from the floor; there was a space of 2 feet 9 inches between the seat and the form in front, and the seat was 2 feet deep.[15] There was but a single row of stalls, and the forms were very low; only 22¼ inches above the platform on which they stood. They are too low to have been used as book rests; which indeed would have been unnecessary, as the monks knew the Psalter and their services by heart; the only service books employed being the big books which lay on the great lectern in the gangway of the choir. It is probable that the forms were of use at certain parts of the service when the monks were _prostrati super formas_.[16] [Illustration: Westminster] At Westminster the original stallwork of the choir has perished; fortunately, however, a sketch of a portion of it has been preserved (31).[17] That the sketch is trustworthy may be seen by comparing it with the description of the stalls by Dart in his _Westmonasterium_ (1742), who says that "the stalls were crowned with acute Gothic arches supported by pillars." The sketch shews slender shafts with molded capitals, neckings and bases, supporting lancet arches which are without cusps; at the back are trifoliated lancets. The work belongs to the period when the eastern bays of the nave were built, viz., 1258 to 1272. In Henry VII.'s chapel are two misericords of conventional foliage; no doubt they belonged originally to Henry the Third's choir. A valuable and little known example of a thirteenth century stall survives at Hemingborough, Yorkshire (87). At Peterborough also fragments of stalls of the same century remain; but they have backing of Jacobean character (32). At Gloucester a fragment of a thirteenth century stall has been preserved behind the seat of the Canon in residence. {32} [Illustration: Peterborough] {33}
