These are the arms traditionally associated with the Chaucer family. In
heraldic terminology, this coat of arms is described as Per Pale Argent and
Gules a Bend Countercharged.
The same coat of arms appears in the top left corner of this portrait of
Geoffrey Chaucer (the fifteenth century painting commonly known as the Harvard
Chaucer Portrait). The arms also appear on
Chaucer's
tomb in Westminster Abbey, London.
