From Dom Guéranger's The Liturgical Year.

ROME, wishing to admit as few interruptions as possible into the present great Octave, gives but a brief notice of St. Hubert in the Martyrology. It is fitting that we should imitate her reserve. Were we, however to omit all mention of him, Christian hunters, so faithful in proclaiming their glorious Patron, would not forgive us. It is right also to satisfy popular piety, and the gratitude of numberless clients saved from hydrophobia, and led to the feet of the Saint by a tradition of a thousand years' standing. A few words suffice to recount his life.

After the mysterious stag had revealed Christ to him, he became, from a hunter of wild animals, a hunter of souls; and merited to be called the Apostle of Ardenne, whose forests had often echoed to the baying of his hounds. He became the disciple and successor of St. Lambert; and transferring from Maestricht both the relics of the holy Martyr-Bishop and the Episcopal See, he raised Liege from an obscure village to a great town. His blessed death took place on May 30th 727; and on November 3rd 743, his precious remains were taken up for the first time, which led to the celebration of his feast on this day. In the following century, the Abbey of Andain was put in possession of the sacred deposit; and took from him the name of St. Hubert, as did likewise the town which sprang up around and soon became a centre for pilgrimages. Two orders of knighthood were established in honour of St. Hubert; the first perished with the fall of the Bourbons its last chiefs; the other still exists, and the kings of Bavaria are its Grand-Masters.
