common for one person to display multiple crests with his arms; certain high-ranking noblemen are entitled to as many as seventeen. This practice did not exist in Britain until the modern era, and arms with more than one crest are still rare. In contrast to Continental practice, where a crest is never detached from its helm, a Briton with more than one crest may choose to display only one crested helm, and have the other crests simply floating in space. Though usually adopted through marriage to an heiress, examples exist of secondary crests being granted as augmentations: after defeating the Americans at the Battle of Bladensburg, Robert Ross was granted, in addition to his original crest, the crest of an arm holding the US flag with a broken flagstaff. After the 16th century, it became common for armigers to detach the crest and wreath from the helm, and use them in the manner of a badge, displayed on crockery, carriage doors, stationery, etc. This led to the erroneous use of the term "crest" to mean "arms", which has become widespread in recent years. Unlike a badge, which can be used by any amount of relatives and retainers, a crest is personal to the armiger, and its use by others is considered usurpation. In Scotland, however, a member of a clan or house is entitled to use a "crest-badge", which consists of the chief's crest encircled by a strap and buckle inscribed with the chiefly motto. Marks of cadency are generally not used with crests, though it is not incorrect to do so, and the British royal family continue this practice. It is, however, widely observed in England that no two families may use the same crest. This is in contrast to Scottish practice, in which crests are less significant, and are often borne in the same form by a great many unrelated people. As a result of this lack of need for differentiation, Scottish crests tend to be less ornamental than their English counterparts. The usual torse around the crest is frequently replaced by some kind of coronet, known as a "crest-coronet". The standard form is a simplified ducal coronet, consisting of three fleurons on a golden circlet; these are not, however, indications of rank, though they are not generally granted nowadays except in special circumstances. In some modern examples, the crest features both a crest-coronet and a torse, though
