Christus was an anonymous figure for centuries, his importance not established until the work of modern art historians. Giorgio Vasari barely mentions him in his biographies of painters, written in the Renaissance, and near contemporary records merely list him amongst many others. In the early to mid-nineteenth century, Gustav Waagen (who identified him in Francophile language as "Pierre Christophsen") and Johann David Passavant were important in establishing Christuss biographical details and in attributing works to him.
