Saint James at the battle of Clavijo (1885) by the Spanish painter José María Casado del Alisal (1832-1886). In the Spanish legend Saint James miraculously appeared to fight for the Christiansduring the battle of Clavijo (844), and became therefore as Santiago Matamoros, or the Moor-slayer the national saint of Spain.
Interesting is that Casado del Alisal did here a kind of history painting instead of a religious one. In this manner he is assuring the "historical reality" of the legend.
