Saint Crispin is a Christian martyr celebrated on October 25. He is known as the patron saint of cobblers, leather workers, and shoemakers. According to tradition, he and his brother, Saint Crispinian, preached Christianity in Gaul (modern-day France) during the Roman Empire. They were eventually arrested and executed for their faith. The story of Saint Crispin emphasizes themes of perseverance and faith in the face of adversity. His feast day is often associated with the Battle of Agincourt in 1415, where King Henry V famously rallied his troops by invoking Crispin's name, highlighting the saint's enduring legacy in English history.
