The chapel is groined in the ordinary manner, the masonry being, as usual, very fine. The ribs are all of the same general section (Fig. 1253, A A), but each set is slightly different in size, the diagonals being the largest. There are no wall ribs. The details of the carved bosses at the intersections are shown in Fig. 1253, B. A stone bench runs [Illustration: FIG. 1256.--Stirling Parish Church. Arms and Initials in St. Andrew’s Chapel.] along the west side only. There is a roughly formed square recess, about 12 inches wide (see Fig. 1248), in the north wall near the east end, and in the east wall at the south-east corner (see Plan and Fig. 1250) there is an ogee-headed recess, about 7 inches high by 5 inches wide and 2½ inches deep, at about 3 feet 6 inches from the floor. There are recesses somewhat similar to the latter at Paisley Abbey. St. Andrew’s Chapel was erected by Duncan Forrester of Garden, Knight, whose initials are cut on the lintel of the west window (see Fig. 1253, C), and his arms, together with a saltier for St. Andrew, are carved on the centre boss (see Fig. 1253, B). The name of Duncan Forrester occurs in charters [Illustration: FIG. 1257.--Stirling Parish Church. Details of Niche in St. Andrew’s Chapel.] relating to Stirling in 1479 and onwards for a period of forty years. He was provost of the town of Stirling, and appears to have been a liberal benefactor to this church. As shown on the Plan there are three interesting grave slabs in the chapel. One of these, of the date 1584, contains the arms of Durham of Grange (Fig. 1254); but as no member of that family had A. D. as initials at that period, the monument may probably have belonged [Illustration: FIG. 1258. Stirling Parish Church. Exterior Base.] to the Durhams of Mollet, one of whom, with the above initials, married Eliz. Murray. This would correspond with the initials and lower shield on the slab (see Fig. 1254) in which the Durham and Murray arms are impaled. The adjoining slab exhibits six shields. One of these contains the founder’s arms (Fig. 1255), and another a curious figure arranged saltier-wise. Nothing can be determined as to the carving on the other shields. The remaining slab contains the arms and initials of Duncan Forrester (Fig. 1256), possibly the son of the founder, and the Erskine arms with the initials M. E. A consecration cross is shown (see Fig. 1253), which is carved on the north wall of the chapel. In Fig. 1257 are shown detached portions of a niche, including the canopy and corbel, lying on the floor. The exterior base of the church, which is partly returned round the west side of this chapel, is shown in Fig. 1258. There were north and south doorways to the nave, opposite each other, in the second bay from the west. The south one had a large porch, now destroyed.
