Plate 51: Constructing the Black Castle, Part 17: what is the actual width of a crenellation?
(This plate added MAR 2004)
|
The crenellation template made by the artisan (see Plate 50 ) provides the relative heights and widths of the merlons and crenellations, but the template provides no information about the actual sizes of these elements of the battlement.
In order to transform the qualitative information provided by the crenellation template, a numerical conversion factor must be calculated. --more-- |

The accompanying photo shows a toy soldier standing upon the wall-walk. An architect's ruler, rotated to the inch-scale, is placed in front of the toy soldier. The ruler indicates that a width of three-quarters of an inch would be adequate for a crenellation, because, in the scale of the toy soldier, three-quarters of an inch represents approximately two feet. Now that we know how wide a Black Castle crenellation should be (three-quarters of an inch), we can proceed with the calculation of a conversion factor. This calculation is explained in the next plate (Plate 52 ).
The soldier in the accompanying photo represents a yeoman warder of the Tower of London. Go to top of page |
