Heraldry encompasses all of the duties of a herald, including the science and art of designing, displaying, describing and recording coats of arms and badges, as well as the formal ceremonies and laws that regulate the use and inheritance of arms. The origins of heraldry lie in the medieval need to distinguish participants in battles or jousts, whose faces were hidden by steel helmets.

Vexillology (from the Latin vexillum, a flag or banner) is the scholarly study of flags, including the creation and development of a body of knowledge about flags of all types, their forms and functions, and of scientific theories and principles based on that knowledge. Flags were originally used to assist military coordination on the battlefield, and have evolved into a general tool for signalling and identification, particularly identification of countries.

Matthew Paris (lit. "Matthew the Parisian"; c. 1200 – 1259) was a Benedictine monk, English chronicler, artist in illuminated manuscripts and cartographer, based at St Albans Abbey in Hertfordshire. He wrote a number of works, mostly historical, which scribed and illuminated himself, typically in drawings partly coloured with watercolour washes, sometimes called "tinted drawings". Some were written in Latin, some in Anglo-Norman or French verse. His Chronica Majora is an oft-cited source, though modern historians recognize that Paris was not always reliable. ( more...)

The Coat of arms of Hungary was adopted in July 1990, after the end of the Socialist regime, although it has been used before, both with and without the crown, sometimes as part of a larger, more complex coat of arms, and many of its elements date back to the Middle Ages. It is usually said that the silver stripes represent four rivers ( Duna, Tisza, Dráva, Száva) and the hills represent three mountain ranges ( Mátra, Tátra, Fátra), but this theory is historically unfounded.

The Raven banner (in Old Norse, Hrafnsmerki; in Old English, Hravenlandeye) was a flag, possibly totemic in nature, flown by various viking chieftains and other Scandinavian rulers during the ninth, tenth and eleventh centuries CE. The flag, as depicted in Norse artwork, was roughly triangular, with a rounded outside edge on which there hung a series of tabs or tassels. It bore a resemblance to ornately carved "weather-vanes" used aboard Viking longships.

Scholars conjecture that the raven flag was a symbol of Odin, who was often depicted accompanied by two ravens. Its intent may have been to strike fear in one's enemies by invoking the power of Odin. As one scholar notes: "The Anglo-Saxons probably thought that the banners were imbued with the evil powers of pagan idols, since the Anglo-Saxons were aware of the significance of Óðinn and his ravens in Norse mythology."
