Sun (heraldry)
The most usual form, often called sun in splendour or in his glory, consists of a round disc with the features of a human face surrounded by twelve or sixteen rays alternating wavy and straight.[2][3] The alternating straight and wavy rays are often said to represent the light and heat of the sun respectively.[4] It was used as a badge by Edward II of England, and was later adopted by Edward IV following the appearance of a parhelion or "sun dog" before his victory at the Battle of Mortimer's Cross in 1461[3][5] (see also Battle of Mortimer's Cross#Parhelion).It also had significance in alchemy, and may be a symbol of the Roman deity Sol Invictus (Unconquered Sun).[6] It is a common charge in the heraldry of many countries, regions and cities: e.g. the bearings of Armstrong family in Canada;[7] the Sun in Splendour appears superimposed on the Cross of St. George and behind the White Rose of York on the flag of the West Riding of Yorkshire; and on the arms of Banbury Town Council,[8] England.
