Not the least remarkable feature in the structure is the range of canopied monuments which stand between the pillars on the north side. In connection with these monuments, the history of the edifice has been ingeniously traced by Mr. Chisholm-Batten.[153] The eastmost monument (see Fig. 808) is traditionally stated to be that of a Countess of Ross; and Mr. Chisholm-Batten, from various indications in the building, shows that it was, in all probability, the Countess Eufamia, daughter and heiress of the Earl of Ross, who erected this aisle, and is buried under the eastern monument therein. This lady was possessed of ample means to erect such a splendid structure. She married, first, in 1366, Walter de Leslie, and succeeded, in 1372, to the estates of Ross. Leslie died in 1382; and in the same year the countess espoused the Earl of Buchan, better known as the “Wolf of Badenoch.” He died in 1394; and thereafter the countess took the veil, and became abbess of the convent of Elcho. Mr. Chisholm-Batten has detected the arms of Leslie, her first husband (on a bend three buckles), on one of the bosses of the vaulting of the western division; while on another boss is carved a bull’s-head caboshed, the arms of Bishop Bulloch, who occupied the see from 1420 to 1439. As the style of the architecture accords with these dates, the inference is that the western part of the aisle was erected either by the countess or her son, Alexander Leslie, Earl of Ross, and completed during the episcopate of Bishop Bulloch, and that the monument to the countess was erected by her son in the noble aisle which she had built, and in which she, no doubt, took great pride. The death of the countess took place before 1398. The aisle would thus date about the end of the fourteenth or the beginning of the fifteenth century, and must be regarded as a splendid example of Scottish architecture of that period. Possibly some portions of the western division are older; but, if so, it has been remodelled and vaulted at the above date. The piers next the nave (Fig. 810) have the peculiar feature of a square plinth (somewhat like the small buttresses which enclose the adjoining tombs) running up the inner side to form a support for the springing of the vaulting (Fig. 810). This feature has the appearance of being an addition to the piers, thus suggesting that the aisle and its vaulting are of later date than the nave of the cathedral. The piers are clustered, and have moulded caps with round abaci. The monument in the western division of the aisle (see Fig. 810) is believed to be that of Bishop Fraser, who occupied the see from 1498 to 1507; [Illustration: FIG. 810.--Fortrose Cathedral.
