The name derives from its shape, which resembles a millrind, moline being the Old French for a mill, the iron clamp of the upper millstone.
It is very similar to one of the varieties of the fer de moline heraldic charge (literally meaning: "iron of a mill"), the forked tips of which however circle out slightly more, akin to the cross recercelee. It is borne both inverted and rebated, and sometimes "saltirewise" (i.e. in the form of a saltire).
The Cross Moline is associated with St. Benedict of Nursia. As a result, it is widely used as an emblem by the monks and nuns of the Order of St. Benedict, which he founded.
