Hola,
For your collection: We found this ex-voto (1713) in La Iglesia de la Asunción in Navarette (a pueblo in La Rioja, on the Camino de Santiago). It was a large (4’ x 3’) framed painting. It reminded us of the ones we had seen in Ecuador.
This one was commissioned by Don Manuel Joseph de Bernabeitia y Coloma, a Caballero in the order of Santiago, to thank the virgin for the miracle that saved him during a storm at sea. Bernabeitia (who died in 1726) served in Mexico City (and most likely suffered the storm on his return), so he was certainly aware of the tradition of the Mexican ex-voto. His son stayed in Mexico and achieved fame as a poet.
