The scallop shell is the traditional emblem of St James the Great and is popular with pilgrims returning from the Way of St James (Camino de Santiago) and the apostle's shrine at Santiago de Compostela in Galicia, Spain.
Medieval Christians would collect a scallop shell while at Compostela as evidence of having made the journey.
The association of Saint James with the scallop can most likely be traced to the legend that the apostle once rescued a knight covered in scallops.
An alternative version of the legend holds that while St. James' remains were being transported to Galicia (Spain) from Jerusalem, the horse of a knight fell into the water, and emerged covered in the shells.

Indeed in French the mollusc itself – as well as a popular preparation of it in cream sauce – is called coquille St. Jacques.
In German they are Jakobsmuscheln – literally "James's shellfish".
Curiously the Linnaean name Pecten jacobeus is given to the Mediterranean scallop, while the scallop endemic to Galicia is called Pecten maximus due to its bigger size.
The scallop shell is represented in the decoration of churches named after St. James, such as in St James' Church, Sydney, where it appears in a number of places, including in the mosaics on the floor of the chancel.

When referring to St James, a scallop shell valve is displayed with its convex outer surface showing.
In contrast, when the shell refers to the goddess Venus (see below), it is displayed with its concave interior surface showing.
