Analysis of information sources in references of the Wikipedia article "Nicholas of Verdun" in English language version.
Lorraine, with Verdun as artistic hub, is thus proven to be the home of the period's finest artisan-artists. Master Nicolas, by his own testimony, came from the town of Verdun, signing his works as NICOLAUS VIRDUNENSIS with his name carefully chiseled in stone. He thus broke with the medieval convention of the anonymous artist and established a precedent for the signature of individual genius, in the renaissance sense of the term.
