The standard corpus of English Romanesque and Gothic mouldings is that of Edmund Sharpe: The Mouldings of the Six Periods of British Architecture from the Conquest to the Reformation, 1871. This work was never completed, and is particularly defective for the period after 1350, also unrepresented in Sharpe's Architectural Parallels, 1848. F. A. Paley's Manual of Gothic Mouldings contains profiles on small and diverse scales, and the sources of many examples are not given; of greater general use is the appendix of mouldings in Francis Bond, Gothic Architecture in England, 1906, but no dates are indicated, and many of the specimens are chosen from buildings of very uncertain date. So far as I am aware, no collection has yet been prepared to illustrate the mouldings used by one master mason or by one school. What follows is an attempt to relate a number of details and mouldings to a particular master and to closely approximate dates. In the hope that similar collections will be formed from the work of other schools, I mention the few rules to which I have adhered:
1. To include as primary evidence details attributable on documentary grounds to a specific master mason.
2. To include for comparison similar details which
(a) can be connected with the master on definite but inconclusive evidence;
(b) are known to be of comparable date;
(c) have peculiarities suggesting a closely cognate origin.
3. To draw all mouldings to a uniform scale of not less than one-eighth full size (1½ in. to 1 ft.).
4. To give the source, date, and master (where known) of each example on the drawing itself.
