Legend had Crispin and Crispinian, noble Roman twin brothers who went to Gaul with St. Quintinus to preach the gospel. They preached covertly during the day and worked as shoemakers at night. They are the patrons of shoemakers, cobblers, and leatherworkers.
A very famous battle in the hundred years war between England and France was fought on St. Crispin's Day in the year 1415. It was called the "Battle of Agincourt" and was a central part of the play "Henry V" written by William Shakespeare.
Shakespeare's play included a motivational speech called the
Crispin's Day Speech. There is a famous line in the poem:
""We few, we happy few, we band of brothers"
and is the origin of the phrase "band of brothers" which has been used in literature and film many times since.
