The two main devices (symbols) in the Wertberg blazon are the bar and wing. The two main tinctures (colors) are gules and or.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P52. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).3A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
Or is the heraldic metal Gold, often shown as a bold, bright yellow colour. It is said to show “Generosity and elevation of the mind” 4The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35. Later heralds, of a more poetic nature liked to refer to it as Topaz, after the gemstone, and, for obvious reasons associated it with the Sun 5Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 6A Complete Guide to Heraldry, A.C.

Parker, Oxford, 1894, Entry:Bar, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). Bars can be a distinctive and easily recognised device, early examples include those awarded by Henry III of England to the family MAUDYT Argent, two bars gules.
Wings are frequently observed in coats of arms. Unless otherwise specified they should be shown as eagle’s wings, with a realistic appearance. 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Wing They can appear singly or in pairs, in which form they are very often found in the crest, which rests above the shield in a full achievement of arms. Wade, quoting Quillim, suggests that the use of the wing on the shield signifies “celerity and protection or covering”. 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P73
