The earliest indication of devotion to St. Expeditus comes only from the second half of the eighteenth century. He was mentioned briefly in 1675 in the "Acta sanctorum" volume for April. However, according to Delehaye, the word "Expeditus" is a misreading of "Elpidius". The name "Expeditus" has provoked puns, so he has become the saint of rapidity. At first, he was invoked for urgent causes; he has since become the patron of dealers, sailors, students, and examinees; he is also implored for success in lawsuits.
