The Bollandists published seven early lives of Hubert (Acta Sanctorum, November 3, 759 – 930 A.D.); the first of these was the work of a contemporary, although it offers few details.

As a youth, Hubert was sent to the Neustrian court of Theuderic III (r. 673–691) at Paris, where his charm and agreeable address led to his investment with the dignity of "count of the palace".

Hubert moved to the Austrasian court where he was warmly welcomed by Pepin of Herstal, Mayor of the palace, who entitled him almost immediately Grand Master of the household.

Hubert renounced all his very considerable honors and gave up his birthright to the Aquitaine to his younger brother, Odo, whom he made guardian of his infant son, Floribert.

In 720, in obedience to a vision, Hubert translated St. Lambert's remains from Maastricht to Liège with great pomp and ceremony, with several neighboring bishops assisting.

A basilica for the relics was built upon the site of Lambert's martyrdom, and was consecrated as a cathedral the following year, the see being removed from Maastricht to Liège, then only a small village.

Hubert actively evangelized among pagans in the extensive Ardennes forests[11] and in Toxandria, a district stretching from near Tongeren to the confluence of the rivers Waal and the Rhine.

Initially he was buried in the collegiate St Peter's Church, Liège, but his bones were transported to the Benedictine Abbey of Amdain in the Ardennes in 825.

Hubert, along with Quirinus of Neuss, Cornelius and Anthony, was venerated as one of the Four Holy Marshals (Vier Marschälle Gottes) in the Rhineland.

In some versions of the story, the stag is said to have lectured Hubert to hold animals in higher regard and have compassion for them as God's creatures with value in their own right.

He ought to shoot only old stags which are past their prime breeding years and forego a much-anticipated shot on a trophy to instead euthanize a sick or injured animal that might appear on the scene.

[7] Such is the legacy of Hubert, which is still taught today and who is held in high regard in the extensive, rigorous German and Austrian hunter education courses.

[citation needed] These hunters apply a specific set of ethics, rituals, rules, and tactics that date from the early Middle Ages.

In Belgium, the feast day of St Hubert (Fête de la Saint-Hubert, in French) is marked by blessings of horses, dogs, and other animals,[21][22] not necessarily those involved with hunts.
