But if there is little variation in plan, there is, as has been noted, even in the simplest towers, some degree of variation in detail. There are cases, moreover, in which the tendency to variation takes the direction of increased ornamental treatment. Instances are quite common in which the heads of the mid-wall shafts, bulging to support their impost-blocks, have been carved into the form of capitals—plain cubical or cushion-blocks, as at Winterton or Clee; rough suggestions of classical volutes and foliage, as at Glentworth or Scartho; varied forms of fruit and leafage, as at Bracebridge; or delicate and cleverly cut relief work, as at St. Peter-at-Gowts. And these capitals are not the only features which show the tendency. At Alkborough ornamental material has been transferred from some deserted Roman villa in the neighbourhood: a cornice from an entablature has been cut up, used as imposts, and turned upside down to form plinths for the jambs of the tower arch. But at Branston, south of Lincoln, the builders have not borrowed ornament. Like the masons at Broughton with their abortive recessed arch, they have tried to copy what they have heard of, what some of them at any rate have seen, and have covered the lower part of the west wall of their tower with arcaded panelling, with rounded arches and cushion capitals. This, and the central doorway with shafting and rudely foliated capitals, have been inspired from a source quite distinct from that which brought into being the strip-work panelling of Barton-on-Humber. We are at once impelled to ask what this source is. And this question brings us to the consideration of two final questions, which are complementary to one another. What influences from the Christian architecture of other countries were felt by Lincolnshire masons? Is there any element of progress to be traced in the Saxon buildings of the county? In short, to combine the two questions into one, can any chronological sequence be traced in these buildings, by comparing them with the work of Romanesque builders in other countries?
