"St. Crispin" refers to a Christian martyr and saint, celebrated on October 25. He is often associated with shoemakers, as he and his brother, St. Crispinian, were said to have been cobblers by trade. They were known for their missionary work in Roman Gaul and were executed for their faith during the reign of Emperor Maximinus II. The story of St. Crispin has inspired various cultural references, including Shakespeare's famous speech in the play Henry V. This speech emphasizes themes of camaraderie and valor, highlighting the significance of the day in the context of the Battle of Agincourt in 1415.
