The work of St. Hugh at Lincoln is of such extraordinary importance to the student of architecture, that it may be well to closely follow an eminent authority in tracing the parts which date from this bishop's time. J. H. Parker, who remarked that the architecture of Lincoln Minster was his favourite study for thirty years, carefully investigated the matter, and the results were published in the 43rd volume of the _Archæologia_. He says that "the work of the time of St. Hugh, A.D. 1192-1200, is pure early English Gothic, and is the earliest building of that style in the world. The French have nothing so early, not even in the royal domain, which is usually cried up as the district of the earliest Gothic in the world. The best-informed French archæologists admit that they have nothing of the character of Lincoln for twenty or thirty years after the time of St. Hugh.... The portion of the cathedral (erected by St. Hugh) consists of the choir ... the aisles to it and the smaller or eastern transept, with the apsidal chapels on the eastern side of that, also two bays on each side of the chancel arch in the great transept; but the walls of the eastern side of that transept only--the the two ends with the wheel windows and the western walls of the transept are of later periods. The original work had thin walls only, with flat buttresses on the outside, and one of the elegant wall-arcades on the lower part of the inside, making the wall still thinner." Mr. Parker also considered that the vaults were insertions of subsequent periods, and that the original building had only a timber roof and a flat wooden ceiling, similar to that which remains at Peterborough. "When the vaults were added it was found necessary to make the walls thicker, and this was done by a casing on the inside; but the builders being unwilling to conceal the beautiful wall-arcade, made another similar to it in the lower part of the new inner wall, exactly like the earlier one against which it is built, but in such a manner as not to conceal it. This arrangement is proved by a flat vertical joint up the middle of the wall, ... not content with this, when the vaults were inserted the architect also placed vaulting-shafts to help to carry those of the aisles, and these descend to the ground. This accounts for the three shafts one in front of the other, which have so long been a puzzle to architects and to students of architectural history. The walls were further strengthened by solid square buttresses built up against the flat ones; these now strong buttresses receive and support the thrust of the vault of the choir, which is carried over the aisle by flying buttresses, with circular openings over the vault of the aisle, built against the inner flat buttress of the inner wall, which had been sufficient to carry the wooden roof, but would not have carried the vault." It may be well to remark here that some authorities have not agreed with Mr.
