Fylfot

Common card · No. 323618

The fylfot or fylfot cross ( FILL-fot) and its mirror image, the gammadion, are types of truncated swastika, associated with medieval Anglo-Saxon culture. It is a cross with perpendicular extensions, usually at 90° or close angles, radiating in the same direction. However – at least in modern heraldry texts, such as Friar and Woodcock & Robinson (see § Bibliography) – the fylfot differs somewhat from the archetypal form of the swastika: always upright and typically with truncated limbs, as shown in the figure at right. The term's most commonly cited etymology derives from a 19th-century misreading of a manuscript, where it was an instruction to fill the foot of a stained-glass window.
