Crancelin

Crancelin (or "crown of rue") is a charge in heraldry, usually seen in the bend on a shield.

It depicts a band of a stylized trefoil leaves, representing a branch of common rue (Ruta graveolens).

[1] Legend has it that at the investiture of Bernhard, Count of Anhalt and Ballenstedt, as Duke of Saxony, the then emperor, Frederick I Barbarossa, took the chaplet of rue he was wearing and placed it over the corner of Bernhard's shield.

To commemorate this act, the crancelin vert was added to the Ballenstedt arms (barry sable and or).

[2] The Encyclopédie of 1751 defined it as a "portion of a crown placed in bend across a shield".
