Isidore the Laborer was a Mozarab farmworker living in medieval Madrid during the late 11th and early 12th centuries. Born to devout parents, he worked as a hired hand on an estate near the city, eventually becoming a bailiff for the landowner. He was known for his deep piety and his generosity toward the poor and animals. Following his death in 1130, he was recognized for numerous miracles, leading to his eventual canonization. He is widely honored as a patron of agriculture and the city of Madrid.
