The west front above the portal and the whole of the nave were reconstructed about the time of Bishop Dunbar (1422-1435), and the chapter-house by Bishop David Stewart (1482-1501). The architecture corresponds with their respective periods, and bears their coats of arms, engraved on each department.[134] Dr. Thomas Chalmers considered the ruins of Elgin to be the finest remains of antiquity in Scotland, and as picturesque in their variety.[135] 6. DIOCESE OF BRECHIN The two bishoprics of Brechin and Dunblane were formed from the old Pictish bishopric of Abernethy, in so far as its churches were not yet absorbed by the growing bishopric of St. Andrews, which immediately succeeded it.[136] Abernethy was the last of the bishoprics which existed while the kingdom ruled over by the Scottish dynasty was called the kingdom of the Picts; St. Andrews was associated with that of the Scots.[137] Abernethy was from the earliest days dedicated to St. Bride, and Panbride in the diocese of Brechin, and Kilbride in that of Dunblane, indicate, in Dr. Skene's view, that the veneration of the patroness of Abernethy had extended to other churches included in these dioceses.[138] From this old Pictish diocese the bishopric of Brechin was formed, towards the end of King David's reign, about 1150.[139] The Church of Brechin has no claim to represent an old Columban monastery:[140] its origin as a church is clearly recorded in the Pictish Chronicle, which states that King Kenneth, son of Malcolm, who reigned from 971 to 995, gave "the great city of Brechin to the Lord," founding a church to the Holy Trinity, a monastery apparently after the Irish model, combined with a Culdee college. We hear of it next in two charters of David I. to the Church of Deer, and in the second of these the "abbot" of the first appears as "Bishop of Brechin" (about 1150). The abbacy passed to lay hereditary bishops, and the Culdees were first conjoined with, next distinguished from, and at last superseded by, the cathedral chapter.[141]
