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.

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.

The Royal Coat of Arms of Canada (known formally as the Arms of His/Her Majesty in Right of Canada) is, since 1921, the official coat of arms of the Canadian monarch, and thus also of Canada. It is closely modelled after the royal coat of arms of the United Kingdom with distinctive Canadian elements replacing or added to those derived from the British.

The maple leaves in the shield, blazoned "proper", were originally drawn vert (green) but were redrawn gules (red) in 1957. A circlet of the Order of Canada was added to the arms for limited use in 1987. The shield design forms the Royal Standard of Canada, and the shield is found on the Canadian Red Ensign. The Flag of the Governor General of Canada, which formerly used the shield over the Union Jack, now uses the crest of the arms on a blue field. (more...)

The flag of Italy (bandiera d'Italia, often referred to in Italian as il Tricolore) is a tricolour featuring three equally sized vertical pales of green, white, and red, with the green at the hoist side. Its current form has been in use since 19 June 1946 and was formally adopted on 1 January 1948.

The first entity to use the Italian tricolour was the Repubblica Cispadana (Cispadane Republic) in 1797, after Napoleon's victorious army crossed Italy. During this time many small republics of Jacobin inspiration supplanted the ancient absolute states and almost all, with variants of colour, used flags characterised by three bands of equal size, clearly inspired by the French model of 1790. The colours chosen by the Republic were red and white, the colours of the flag of Milan, and green, which was the colour of the uniform of the Milanese civic guard. Some have attributed particular values to the colours, and a common interpretation is that the green represents the country's plains and the hills; white, the snow-capped Alps; and red, blood spilt in the Wars of Italian Independence. A more religious interpretation is that the green represents hope, the white represents faith, and the red represents charity; this references the three theological virtues. (more...)

Heraldry in its most general sense encompasses all matters relating to the duties and responsibilities of officers of arms. To most, though, heraldry is the practice of designing, displaying, describing, and recording coats of arms and badges. Historically, it has been variously described as “the shorthand of history” (Fox-Davies) and “the floral border in the garden of history” (Moncreiffe & Pottinger). The origins of heraldry lie in the need to distinguish participants in combat when their faces were hidden by iron and steel helmets. Eventually a system of rules developed into the modern form of heraldry. Though heraldry is nearly 900 years old, it is still very much in use. (more...)
