After this period a few additions still continued to be made to the fabric. A small chapel, called the Chepman aisle, was thrown out from the Preston aisle close to the south transept. It measures about 14 feet long by 12 feet wide, and opens from the Preston aisle with a pointed arch (Fig. 847). The ceiling is formed with a pointed barrel vault, ornamented with cross ribs, which spring from large carved corbels. This chapel was founded and dedicated to St. John the Evangelist by Walter Chepman, called the Scottish Caxton, from his having, in 1507, introduced the art of printing into Scotland. St. John’s emblem of the eagle (Fig. 848) is carved on one of the corbels of the roof. Chepman’s enterprise was greatly encouraged by James IV. and his Queen Margaret; and, in thankfulness for the royal patronage, this chapel was dedicated by Chepman, on 21st August 1513, to the welfare of the souls of the king and queen, and their offspring. This happened within a month of James’s death at Flodden, on 9th September 1513. Chepman himself was buried in this aisle in 1532. The south transept seems to have been extended southwards when the two chapels last mentioned were erected. [Illustration: FIG. 846.--St. Giles’ Collegiate Church. Mouldings of Monument.] The only part of the interior of the structure still unmentioned is a chapel to the east of the north transept. This building was at one time used by the Town Clerk as his office, and contained several stories and a staircase. It is said to have been erected after the Reformation, but it was altered, having large windows inserted, and was connected with the church as a vestry in 1829. It has recently been set apart to contain the monument of Dr. Wm. Chambers, to whose liberality the city is indebted for the complete renovation of the ancient cathedral. In 1829 the church was entirely renewed as regards the exterior, when two chapels to the south of those built in 1389 and the south porch were [Illustration: FIG. 847.--St. Giles’ Collegiate Church. The Chepman Aisle, from the Preston Aisle.] removed. The round arched doorway of the south porch (Fig. 849) was again erected between the north pillars of the crossing as the entrance to the central division of the church. It has now been transferred to the entrance doorway to the royal pew at the east end of the Preston aisle. Fig. 850 shows the carved ornaments of this doorway, which are all in the decorated style of its period. [Illustration: FIG. 848.--St. Giles’ Collegiate Church. Chepman Aisle: Corbel of Vault.]
