The two main devices (symbols) in the Gutte blazon are the fish and antlers. The main tincture (color) is azure.
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.
Fish in great variety abound in Heraldry, many different species inhabit coats of arms 3Understanding Signs & Symbols – Heraldry, S. Oliver & G.

Parker, Oxford, 1847, P137 that a child might draw. The actual name used in the coat of arms may be some play-on-words or allusion to the family name, as in the famous arms of the de Lucy family, being “Gules, three lucies or”, 5Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 79 this being an ancient name for the fish we call today a “pike”.
The magnificent antlers of the stag are known in heraldry as attires, which can appear as a charge on their own (usually with part of the scalp attached) 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:attire, or a stag may be attired of a different colour. Like many similar forest creatures, stags and their antlers are probably intended to represent pleasure taken in the hunt. 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P30
