Heraldic Roundel with Arms of the Canton of Zürich, 1593. The large shield at center incorporating the double eagle (insignia of the Holy Roman Empire) is surrounded by thirty small shields-those of the wards of the city of Zurich. In the late 1400s, it was customary for neighboring Swiss towns and cantons to exchange panels of stained glass to promote closer political relationships.
