Cartão Saint Barbara with chalice and cannon

Saint Barbara with chalice and cannon. Saint Barbara is venerated by Catholics who face the danger of sudden and violent death at work. She is invoked against thunder and lightning and all accidents arising from explosions of gunpowder. She became the patron saint of artillerymen, armourers, military engineers, gunsmiths, and anyone else who worked with cannon and explosives. Following the widespread adoption of gunpowder in mining in the 1600s, she was adopted as the patron of miners, tunnellers, and other underground workers. As the geology and mine engineering developed in association with mining, she became patron of these professions.
