HOLY ROMAN EMPIRE COAT OF ARMS doesn't have any arrows that I can see, but there is a lot to look at.
here is translation
he Holy Roman Empire (Latin Sacrum Romanum Empire) was the official name for the domain of the Roman-German emperors from the Middle Ages to 1806. The name of the empire derives from the claim of the medieval rulers to continue the tradition of the ancient Roman Empire and to legitimize the dominion as God's Holy Will in the Christian sense. To distinguish it from the German Reich, founded in 1871, it is also referred to as the Old Reich.
The empire was formed in the 10th century under the Otton dynasty from the former Carolingian East Franconia. The name Sacrum Imperium is documented for 1157 and the title Sacrum Romanum Imperium for 1254. Since the late 15th century, the addition of the German Nation (lat. Nationis Germanica).
Due to its pre- and supra-national character, the empire never developed into a nation-state of modern character, but remained a monarchically-run, state-influenced structure of emperors and imperial estates with only a few common imperial institutions.
The extent and boundaries of the Holy Roman Empire changed considerably over the centuries. In its greatest extent, the empire covered almost the entire territory of today's Central and Parts of Southern Europe.
Since the early modern era, the empire has not been structurally capable of offensive warfare, expansion of power, and expansion. Since then, legal protection and peacekeeping have been regarded as its essential purposes. The empire was to ensure calm, stability and the peaceful resolution of conflicts by curbing the dynamism of power: it was to protect subjects from the arbitrariness of the landlords and smaller imperial estates from violations of the law by more powerful estates and the emperor. Since 1648 neighboring states were also integrated into its constitutional order as imperial estates, the empire also fulfilled a peacekeeping function in the system of European powers.
The fact that since the middle of the 18th century the Empire has been less and less able to protect its members against the expansionary policies of internal and external powers was its greatest deficit and one of the causes of its demise. Due to the Napoleonic Wars and the resulting foundation of the Rhine League, it had become almost incapable of action. The Holy Roman Empire of the German Nation was extinguished on 6 August 1806 with the resignation of the imperial crown by Emperor Franz II.
