In the north wall of the chancel are two recessed tombs (Figs. 1177 and 1178). These monuments, judging from the disturbed appearance of the surrounding masonry and from the different character of the two designs, were apparently not original parts of the chapel, but were subsequently inserted as the occasion arose. The arch stones of the westmost tomb (see Fig. 1177), that of Sir John Forrester (the eldest son of Sir Adam) and his wife, are cut away or concealed by the west wall of the chapel, an arrangement not likely to have been adopted had the tomb been erected when the chapel was built. This monument is usually called the Founder’s Tomb, from the circumstance that Sir John founded the collegiate church. He was twice married: first, to Jean Sinclair, daughter of Henry, first Earl of Orkney; and, second, to Dame Marion Stewart, Lady Dalswinton, widow of Sir John Stewart.[112] His effigy rests on the tomb, along with that of one of his wives. Sir John died after the year 1444. The eastmost tomb (see Fig. 1178) is that of the son of the foregoing, also Sir John, who died before 1454. It contains his effigy and that of his wife. It does not appear to be known to what family the lady belonged; but from the heraldic blazons (to be afterwards described) she seems to have been a member of the Wigmer family. There is another tomb situated in the south transept (Figs. 1179 and 1180). It is believed to be that of Sir Alexander Forrester, son of the last mentioned Sir John. The date of his death is not recorded, but he is known to have been alive in 1467. It contains his effigy only. There has been a finial on the tomb, which is now gone. The amount of heraldic carving on the above tombs, on the gable of the south transept (Fig. 1181), and on the western porch (Fig. 1182) is considerable and is well preserved.[113] The arms represented on the various shields throughout the whole series comprise, for the different members of the Forrester family above mentioned, FORRESTER OF CORSTORPHINE, viz.:-- Argent, three hunting horns stringed sable. These occur alone and conjoined with the arms of their wives, viz.:-- I. Sinclair, Earl of Orkney. 1st and 4th. Azure, a lymphad within a double tressure, flory counter flory, or (for Orkney). 2nd and 3rd. Argent, a cross engrailed (for Sinclair). II. Stewart of Dalswinton. Or, a fesse chequé azure and argent, surmounted of a bend engrailed gules. III. Wigmer. Argent, on a bend sable a ribbon dancettée of the field. IV. Forrester (differenced with Sinclair--probably an unauthorised coat). Argent, a cross engrailed and couped between three hunting horns sable. The above arms are distributed as follow on the three tombs-- FIRST TOMB, SIR JOHN FORRESTER (see Fig. 1177). 1st shield. Forrester.
