[Illustration: FIG. 1129.--The Collegiate Church of Dalkeith. The Eastern Apse.] The buttresses (Fig. 1132), like those of Rosslyn, are massive, and although they have five or six stages, they do not recede at these stages till the wall head is nearly reached, where they are finished with a gablet beneath which a large gargoyle is projected. The buttresses were crowned with square pinnacles, finished with crockets and finials, only two of which now remain, in a very ruinous state. They have been carefully wrought on the inside, so as to adjust themselves to the sloping flanks of the stone roof, the water from which was conveyed through the buttresses by the projecting gargoyles to the ground. There is a canopied niche on the face of all the buttresses, as well as those on each side of the south doorway. A monument in the choir (Fig. 1133) contains two recumbent figures, a husband and wife side by side. The effigies (Fig. 1134) are not recessed, as is frequently the case in an arched tomb in the wall, but lie in the open church where shown on the ground Plan, and they appear to be [Illustration: FIG. 1130.--The Collegiate Church of Dalkeith. Interior of Apse.] in their original position. From the heraldic coats on the monument (see Fig. 1133) it is obvious that the knight was a Douglas, and that the lady was of royal descent. On a lozenge at the head of the knight are the [Illustration: FIG. 1131.--The Collegiate Church of Dalkeith. South Doorway.] arms of Douglas of Dalkeith, viz., two stars on a chief. And on a similar lozenge at the head of the lady are the same arms impaled with those of Scotland (Fig. 1135). The same arms are also repeated at the sides of [Illustration: FIG. 1132.--The Collegiate Church of Dalkeith. North-East Side of Apse.] the monument (see Fig. 1133), with what appear like coronets above them, from which Mr. James Drummond[97] gives it as his opinion that the persons represented are James, 4th Lord of Dalkeith, who was created Earl of Morton in 1457, and his wife Johan, third daughter of King James I. The former died about 1498. Mr. Drummond supposes the lady survived her husband, but the Lady Johanna must have died before the year 1490.[98] The facts on which that view is founded are the presence of the royal and Douglas arms impaled, and “the male figure being sculptured with an earl’s coronet, to which none of the previous lords of Dalkeith had a right, although they were allied to royalty.”[99] [Illustration: FIG. 1133.--The Collegiate Church of Dalkeith.
