The antient usage in bearing of such ensigns of honour as are commonly call'd arms. With a catalogue of the present nobility and baronets of England
A 1682 Oxford heraldry treatise by Sir William Dugdale, printed by M. Pitt, explaining the ancient usage of coats of arms for English nobility and baronets. The hand-coloured shield illustrations show heraldic charges in red, green and silver for a readership of gentry and scholars. A designer might take the bold interlocking patterns and simplified stylised emblems as models for compact, flat, repeatable motifs.
