roundle

The Roundle is a simple circular charge that can occur in great profusion and in a variety of colours A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Roundle. Indeed, so important is this charge that special terms have been developed for each particular colour, for example the pomeis for the green roundle and the plate for the white version. There is also a visually striking version of the roundle known as a fountain, which is a circle coloured with bars wavy alternately argent and azure representing the water at the bottom of a well A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Fountain.
