Mungo's early church, of wood and wattles or of stone, on the banks of the Molendinar, is shrouded in the mists of antiquity until the first quarter of the twelfth century, when David, Prince and Earl of Cumbria, the youngest son of Queen Margaret, took measures to reconstruct the see and recover its property. Of Glasgow during the Culdee period nothing can be definitely known. The result of Prince David's inquest is contained in the _Register_ of the Bishopric,[50] and it sets forth that Prince David, from love to God and by the exhortation of the Bishop, having caused inquiry to be made concerning the lands belonging to the church in Cumbria, had ascertained that they belonged to the church of Glasgow, and restored them. These lands extended from the Clyde on the north to the Solway and English March on the south, from the western boundary of Lothian on the east to the river Urr on the west, including Teviotdale, and comprehended what afterwards formed the site of the city of Glasgow.[51] The building of the cathedral would appear to have been begun before David succeeded to the throne in 1124, and he appointed his tutor John (called Achaius) to the bishopric. In 1136 the church, which was probably chiefly of wood, was dedicated, and King David endowed it further with lands, tithes, and churches. The church of Achaius was destroyed by fire, but through the exertions of Bishop Joceline a society was founded to collect funds for its restoration, and the work was sufficiently advanced for its consecration on 6th July 1197.[52] Although built at different dates, the building has a very homogeneous appearance, and might be mistaken for a building of one period. Under competent guidance,[53] we now propose to give a short sketch of the cathedral itself.
