The main device (symbol) in the Janina blazon is the border. The two main tinctures (colors) are purpure and gules.
The pattern engrailed is a series of scalloped indentations with the points facing outwards – and should not be confused with invected, which has the points facing inwards! Wade believes that both of these indented forms represent “earth or land”, and one perhaps can indeed see the furrowed earth embodied in them.
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.3A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P77.
The border, (sometimes bordure) is a band running around the edge of the shield, following the edge contours and being differently coloured, possibly holding a series of small charges placed on top of it 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Bordure. According to Wade, the bordure itself has no direct meaning, but is perhaps a container for the meaning of its colour or those additional charges placed upon it 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P50
