 The title recalls the name of the very same ancient Roman temple.The baroque palace of the Marquesses of San Isidro was, before a heavy fire in 1942, located at an emblematic spot where the Spanish troops first rebelled against Napoleon in León.There is also an avenue in the same city, named after the third Marquess of San Isidro, Santos Rui-Gómez, who perished in battle fighting for Spain's independence from the French in 1813.
