The feast of St. Crispin and St. Crispinian is observed on Oct 15. The veneration of their burial place is attested by a 6th-century church in Soissons, where (according to the legendary Passio) they suffered martyrdom during the reign of Diocletian, after having made shoes for the poor without charge. In the 9th century, relics came to Osnabrück and they became that city's patron saints. Since the High Middle Ages, they have been venerated as the patron saints of shoemakers, tanners, and saddlers.
