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.

The seal of Indiana is used by the Governor of Indiana to certify official documents. The seal has gone through several revisions since the region was a part of the Northwest Territory. It is likely the original seal, which is similar to the current one, was created by William Henry Harrison during his administration of the Indiana Territory. The current design of the seal was standardized by the Indiana General Assembly in 1963.

The Black Swan is an important cultural reference in Australia, although the character of that importance historically diverges between the prosaic in the east and the symbolic in west. The Black Swan is also of spiritual significance in the traditional histories of many Australian Aboriginal peoples across southern Australia.

The Black Swan is the official state emblem of Western Australia, and is depicted on the Flag of Western Australia, as well as being depicted on the Western Australian Coat-of-Arms. The symbol is used in other emblems, coins, logos, mascots and in the naming of sports teams. ( more...)

The national flag of Singapore was first adopted in 1959, the year Singapore became self-governing within the British Empire. It was reconfirmed as the national flag when the Republic gained independence on 9 August 1965. The design is a horizontal bicolour of red above white, charged in the canton by a white crescent moon facing, toward the fly, a pentagon of five small white five-pointed stars. The elements of the flag denote a young nation on the ascendant, universal brotherhood and equality, and national ideals.

The national flag is not used as an ensign by vessels at sea. In its place, one of three derivatives of the national flag is used, depending on a vessel's status: merchant vessels and pleasure craft fly a civil ensign of red charged in white with a variant of the crescent and stars emblem in the centre; non-military government vessels such as coast guard ships fly a state ensign of blue with the national flag in the canton, charged with an eight-pointed red and white compass rose in the lower fly; and warships fly a naval ensign similar to the state ensign, but in white with a red compass rose emblem.
