When and by whom was the Exsultet written? On Wikipedia I found the Latin text of the Exsultet, but it is not clear when exactly it was written, or by whom.  What is its origin?
According to Zenit and the Catholic Encyclopedia, the solemn rite originated no later than the late fourth century, with the current text of the Exultet likely dating back to the fifth century.  The earliest extant manuscript is found in the Bobbio Missal, dating from the seventh century.  Its author is unknown.
