At Hugh's death the work did not lie neglected long, if at all. A letter was issued in December 1205, appealing for help on behalf of the _novum opus_ at Lincoln. The "Brotherhood of the Church of Lincoln" was offered to those who would contribute; in this way they became enrolled for a certain number of years among those who were specially named in the prayers of the church. The western transept was completed during the early years of the thirteenth century, and the nave constructed, replacing the Norman work of Remigius. The designers here profited by the experience of the past. The vaulting shews a great improvement, and the whole work is of such superior skill as to earn the high praise of the late Professor Freeman, who says that "there are few grander works in the style of the thirteenth century than Lincoln nave, few that shew greater boldness of construction and greater elegance of detail." The nave appears to have been carried steadily onwards to the completion of the first five bays, at which point a curious irregularity is perceptible. The vault suddenly falls two feet lower, and its axis is turned slightly northwards, ultimately falling in with the old west front. The span of the last two bays is also lessened. Perhaps a slight error was made in the direction of the nave at first, which became more evident as time went on, so as to necessitate the change. It has, however, also been suggested that the first intention may have been to remove the west front of Remigius altogether, and to build another at a somewhat different angle farther westwards. If this was the case, economical reasons probably occasioned the change of design, and secured the preservation of a most interesting relic of Remigius' church. It should be remarked that some authorities consider these narrow bays to be no later than the others, and that the work was carried on at both ends of the nave simultaneously, finally meeting towards the middle. There is no document remaining which records the precise date of the erection of the nave at Lincoln, but it would not be difficult to shew that the first half of the thirteenth century practically covers the whole period of its construction. Very little, if any at all, can have been built before the death of St. Hugh in the year 1200, and it was undoubtedly finished before the Angel Choir was begun in 1255. Precentor Venables mentions that Bishop Hugh de Wells, in his will dated 1233, bequeaths 100 marks to the fabric of his church at Lincoln, as well as all the felled timber of which he might die possessed, through all his episcopal estates. He draws the conclusion that the legacy of so large a quantity of timber points to there being a good deal of roofing going on at the time. A new central tower was also begun about this time; it fell in 1237-9, and was replaced by a third, which still stands.
