sacristy or some such apartment; and projecting tusk stones in the corner outside the door show that such a building was contemplated. The chancel (Fig. 1159) is lighted by small widely splayed windows on each side, and three lintelled windows in the east end (Fig. 1160). Mr. Mackenzie shows reasons for believing that this gable has been reconstructed, and that it originally had only two windows in the lower part, with perhaps some kind of central window at a higher level, something like what is found at Mortlach. The pointed piscina (Fig. 1161) beneath the eastmost south window (see Fig. 1160) has, as usual, been mutilated. [Illustration: FIG. 1158.--The Collegiate Church of Arbuthnott. View from South-West.] To connect the chancel with the Arbuthnott Aisle a round archway (see Fig. 1160), 7 feet 8 inches wide, has been cut through the chancel wall. The details of this arch are shown in Fig. 1162. This chapel or aisle, which has an apsidal south end, measures about 20 feet 3 inches long by 12 feet 11 inches wide, and has a vaulted stone roof (Fig. 1163) about 18 feet high, with a semi-octagonal dome over the apse. This view gives an idea of the appearance of the interior of the chapel. In front of the apse windows stands a sarcophagus 6 feet 2 inches long by 2 feet 2 inches wide, having a rude recumbent figure on the top. It contains the following arms on the front, beginning at the head, viz., Douglas, Arbuthnott, Arbuthnott, Stewart; and there appear to be indications that there have been other shields, now cut away. There is a round arched entrance door to the aisle on the west side (see Fig. 1157), with a stoup beneath the adjoining window on the inside, and in the east wall are the remains of a credence. A turret staircase (see [Illustration: FIG. 1159.--The Collegiate Church of Arbuthnott. View from North-East.] Fig. 1157) gives access from the aisle to a priest’s chamber on the upper floor, which Bishop Forbes, believing it to have been the place where the Missal referred to below was written, describes at some length.[107] It had a strong door, which folded back into a recess. The room is of the same size and shape as the aisle below, and is lighted with three windows with square heads, two in the apse, and one (the largest) looking towards the west (see Fig. 1157). The latter is strongly guarded with an iron grating of the usual construction. The windows are fitted with seats like those commonly found in the castles. “There is a stoup for holy water at the [Illustration: FIG. 1160.--The Collegiate Church of Arbuthnott. Interior of Chancel.] entrance, and a small ambry, ornamented with a single trefoil, probably for the reservation of the holy Eucharist.”[108] [Illustration: FIG. 1161.
