(Lat. *collare*; from *colllum*, the neck). Among the ancients, this was sometimes worn as a badge of servitude. The knights of several orders wear a chain of gold, enamelled, and frequently set with ciphers or other devices, with the badge of the order appended to it. Thus, the collar of the order of the garter consists of S.S., with roses enamelled red, within a garter enamelled blue, to which is appended the figure of St George.

Knights of the Collar, a military order in the republic of Venice, called also the order of St Mark, or the Medal. The knights wore no particular habit, and were distinguished only by the collar, which the doge put around their neck, with a medal, on which was represented the winged lion of the republic.
