A beacon is a signal tower, consisting of a pole with a fire-basket at the top, and a ladder on one side for those who feed the fire. It is always drawn flammant, but the fact is often explicitly blazoned. The beacon is found in the arms of Daunt, c.1510 [DBA1 106], but it’s better known as one of the badges of Henry V, d.1422 [HB 110]. See also brazier, lighthouse, torch (cresset).
