Compone

coat of arms of Beaufort, earls and dukes of Somerset, being the royal arms of England differenced with a bordure compony argent and azure

In heraldry, an ordinary componé, compony or gobony is composed of a row of panes of alternating tinctures; the ordinary thus affected is most often a bordure.

The Capetian counts of Évreux differenced the French royal arms with a bend compony.

Certain charges cannot be compony, for practical reasons, such as, in general, common charges, and the chief as they are generally not long and thin as a row of compony is.

Usually only two tinctures are used, but the arms of Formia, Italy, show an unusual bordure which could be blazoned compony of 24 vert, gules, argent, vert, argent, gules.

A variant is counter-compony, with two rows of panes.

A bend or fess billety-counter-billety is, in effect, chequy of three rows of stretched (rather than square) panes, as in the arms of Cullimore in Canada: Azure; a fess billetty counter billetty gules and argent, between, in chief, two crescents and, in base, a wheel or; a bordure or for difference (to be found in the Scots Public Register, vol 52, p 82).

Sometimes compony-like arrangements, such as in the arms of the Duke de Vargas Machuca,^[1] are not so described in blazon. The coat of arms of the 108th Aviation Regiment of the United States Army is blazoned bordered gyronny of ten; in most cases a bordure gyronny would not be distinguished from a bordure compony.
