Coats of arms, which although not initially the exclusive trappings of the nobility subsequently became closely associated with it, reached their apogee in the 9th / 15th and 10th / 16th centuries, as can be seen from their widespread use and application to a range of objects, including commissioned ceramic items. The cartouche bearing Christian inscriptions, a device closely related to heraldry, also appears in
Mudéjar ceramics.
