One of the lesser things lost with the abolition of the Austro-Hungarian Empire in 1918 was its spectacular heritage of heraldry. Very few current monarchies (excepting the United Kingdom) have any such heraldry worth boasting about. For those unaware of the subject, a cursory introduction is in order. Heraldry is the art pertaining to a person's coat of arms. Now, the coat-of-arms originated in Medieval Europe, when knights would cover their armor with cloth of a particular pattern and/or color (hence, the arms or armor, was being coated). This practice allowed the knights to be easily identified upon the battlefield. Eventually, arms became hereditary and a complex array of rules were drawn up to govern the awarding of arms to a person of a subsequent generation. A highly intricate system of symbols and colors also developed, often pertaining to a person's geographical origins or personality traits (a fleur-de-lys for France, or a dog for loyalty, for example).

In the arms of Austria-Hungary as they were immediately prior to its dismemberment by the Allies, we see a pictoral microcosm of the empire and of the ruling house of Habsburg. To the left, we see the arms of Austrian portion of the empire, with the black double-headed eagle supporting the minor arms of the constituent Austrian regions. On the right are the arms of the Kingdom of Hungary, surmounted by the sacred crown of St. Stephen with its characteristic bent cross. In the center are the arms of the house of Habsburg, whose members were of course both Emperor of Austria and King of Hungary simultaneously. Thus, by looking at the entire composition, we can visually understand the government of the realm. We can add a layer of insight by translating the motto "Indivisibiliter ac Inseparabiliter" which means "Indivisible and Inseparable" which underscores the union of the disparate ethnicities under a single monarch.
It is somewhat of a tragedy that such emblems have, by and large, ceased to exist. We have become an extremely literal and word-oriented culture, and the ancient language of symbols is largely foreign to the modern mind.
