Heraldry
My reworking of the examples found in the stunning 1550-1555 anonymous manuscripts, "Insignia pontificum Romanorum et cardinalium II. Insignia ab Urbano VI ad Robertum de Nobilibus cardinalem" (BSB Cod.icon. 267) and "Insignia ... XII. Insignia Florentinorum" (BSB Cod.icon. 277), both at the Bayerische Staatsbibliothek in München.
