It was initially proposed, by Betty Kurth in 1922, that the artist was French and had some association with the court in Paris. Other writers have disagreed, and various nationalities including French, Austrian, German, or Bohemian have been posited for the Master. Some have further suggested that he was an itinerant court artist, trained in France but active in Austria. Various clues have been used in an attempt to describe his nationality. These include his use of finely-worked gold decoration, in which some have seen a link to Franco-Burgundiangoldsmith's work of the late 14th century. Others, instead, see it as a link to the school of panel painting then active at the court in Prague. Consequently, it seems highly unlikely that the artist's nationality will be conclusively established.
Stylistically, the Master's work is distinguished by use of some Gothic decorative elements, as well as oddly-proportioned figures with long, thin limbs and fingers.
