"Hubertus or Hubert (c. 656 – 30 May 727 A.D.) was a Christian saint who became the first bishop of Liège in 708 A.D. He is ...
the patron saint of hunters, mathematicians, opticians, and metalworkers. Known as the "Apostle of the Ardennes", he was called upon, until the early 20th century, to cure rabies through the use of the traditional Saint Hubert's Key.
Hubert was widely venerated during the Middle Ages. The iconography of his legend is entangled with the legend of the martyr Saint Eustace. The Bollandists published seven early lives of Hubertus (Acta Sanctorum, November 3, 759 – 930 A.D.); the first of these was the work of a contemporary, although it offers few details." - (en.wikipedia.org 10.08.2021)
