... The bear was not in any remarkable favour at Rome; but the semi-Romans adopted Ursus as a favourite among their names.  Ursus and Ursinus were early Gallic bishops. (History of Christian Names, Yonge, 1884)

St. Ursus brings a fountain of water from a rock (sixth century).  St. Ursus was a native of Ireland, but quitted his native land and was made archdeacon of Aosta.  One hot summer he heard the rustics of Busseia complaining of thirst, and lamenting the want of water in the neighbourhood.  He called to mind the text that "all things are possible to him who believeth," and forthwith struck with his staff the rock on which he was standing.  Immediately there flowed from it a spring of delicious water, which runs in a liquid stream even to the present day, and is called "St. Bear's Fountain."  Mention is made of it in the archives of the chapter under the title of 1290, where it is stated that "one Jacquemet gave to St. Bear's church a parcel of land situate in the locality of St. Ursus' Fountain."
