The two main devices (symbols) in the Melveton blazon are the inkmoline and plate. The two main tinctures (colors) are azure and argent.
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 1A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Azure. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
Argent is the heraldic metal Silver and is usually shown as very pure white. It is also known more poetically as pearl, moon (or luna) 3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
The mill-rind, also known by a rather surprising number of names (fer-de-moline, inkmoline, mill-ink amongst others) is a distinctive symbol, but hard to place by modern viewers. It is a square or diamond shape with arms extending above and below and in fact represents the piece of iron that connects a circular timber axle to a mill-stone, used for grinding corn. 5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Fer-de-moline These would obviously have been more familiar to those of the middle ages than they are today.
For easy recognition of the items on a coat of arms, and hence the quick identification of the owner, bold simple shapes are best. Hence, simple geometric shapes are often used for this purpose 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146 One of the simplest such shapes is the plain circle, known to heralds as the roundle. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Roundle So popular is this charge that a shorthand has arisen for roundles of a particular colour and plate is a roundle argent, or white. Most authorities agree that the English usage signifies the “Manchet cake” or communion wafer and thus is a symbol of religious allegiance.
