The main device (symbol) in the Drogomir blazon is the three legs conjoined. The main tincture (color) is gules.
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.
Heraldry is a human art, by and for people and it is not surprising that people themselves are frequently depicted in arms 4Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P174. Often these are images of knights and men-at-arms, or individual limbs, such as the “three armoured right arms argent” shown in the arms of Armstrong 5Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 60. As well as the nobility however, we also see both the mundane, ploughmen, fishermen and reapers; and the exotic in the form of club wielding savages and the Moorish or Saracen gentleman with his decorative wreathed turban 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P168. The three legs conjoined is a typical example of this use of the human figure.
