Marianus Sanctus Barolitanus popularized the operation of lithotomy introduced by the father of Giovanni Vigo of Rapallo. This method passed on to Giovanni di Romani and from him to Marianus. It became known as the “Marian operation” and was the forerunner of the more modern lateral lithotomy. Digital facsimile from Google Books at this link.
