Santiago — Saint James — can be found in several different guises. There’s James at the Transfiguration; my favourite, James as a medieval pilgrim; and this version I found in Barcelona on what was probably a church belonging to the military Order of Santiago, Santiago Matamoros, Saint James the Moor-slayer.
James as a bloodthirsty slayer of Muslims, very medieval and crusade-y, no? Well, no, or at least, not as much as you might expect. While the ideas behind this image come from the time when Christians and Musims fought for contro of the peninsula, most of the actual images showing James on a horse, trampling a beleaguered Moor actually date from a time after 1492, the date when the Muslims lost control of Granada, their final stronghold in the peninsula. This one is dated 1580.
I guess it is easier to imagine yourself as a valiant slayer of infidels once they have already been soundly vanquished.
