The Occitan cross, also called the Cross of Toulouse or the Cross of Languedoc, is first of all a heraldic figure. Heralds describe it in a single line: 'Gules, a cross clechée, voided and pommetty Or', in other words a gold cross on a red field. It has twelve pommels, three at the end of each of its four arms. In the Song of the Albigensian Crusade, it already has a name, the crotz ramondenca, the cross of the Counts Raymond.
Each word of the blazon has a precise meaning. Voided: the cross is hollowed out, letting the field of the shield show through. Clechée: its ends curve like the bow of an old key, clé in French, which may be where the name comes from. Pommetty: each point ends in a small ball. This silhouette, both cut-out and rounded, explains why it can be recognised from afar, and why it lends itself so well to relief.
