Styles of Crosses from 'On Diverse Signs Depicted in Arms', in Nicholas Upton's Treatise on Arms and Military Offices
Medium: Ink and pigments on vellum
Bound into a volume containing manuscripts owned by the 16th-century collector, Robert Cotton, this is a page of a treatise on military arts, arms and heraldry by Nicolas Upton, a canon at Salisbury (became precentor 1446) and Wells cathedrals and the foremost English authority on heraldry in his day. It is uncertain where the manuscript was made.
In Upton's reference work on heraldry, this page explains and illustrates different kinds of crosses used in arms, beginning with the George cross and continuing through crosses known as equali, potente and plana cordata.
