This large drawing appears to show a novel design for a revolving, circular wooden floor that could be turned with a hand-operated cogwheel. Such movable floors would have been used within fortified towers, to allow cannons to be rotated in any direction to fire through embrasures in the walls of the structure.
By the same hand as the present sheet, and of similar technique and dimensions, are two closely-related drawings that were likewise at one time in the collection of the 1st Duke of Wellington; one depicting a plan and section of a rotating wooden floor equipped with cannons, and another showing a plan, elevation and section of a fortified round tower with a revolving floor.
Thence by descent to Brigadier Arthur Valerian Wellesley, 8th Duke of Wellington, Stratfield Saye House, Hampshire
