A flag is a piece of cloth attached to a pole, allowed to fly in the breeze. Flags are normally found as artistic details on castles, ships, &c; they’re usually termed “pennons” in such cases. However, flags are sometimes found as charges in their own right. Flags stream to dexter by Society default.
There are some other special terms for different types of flags: A “banner” is a square or rectangular flag on a staff, as in the civic arms of Würtzburg, 1413 [Conz.Const. cvi]. A “gonfanon” is a rectangular or heater-shaped flag, hung from ropes at its top corners, as in the arms of the Counts of Auvergne, c.1275 [Asp2 220]. A “wyn” is a stiff triangular vane; it is mostly used for the sake of a cant.
In Society armory we find the “vexillum”, a standard borne by maniples of the Roman army; it denoted lesser rank than the aquila or eagle standard.
Flags are considered a medium for heraldic display. Thus when used as a charge in Society heraldry, the design on a flag is also checked for conflict. An uncharged flag is not considered presumptuous.
