Artists

The sheer amount of these portraits and their unavoidable similarities led historians to believe that they were mass produced in workshops, where artists would work from templates of common facial features to churn out large amounts of these paintings. Some groups of portraits have been attributed to the same artist, but no one can say for sure. 

It has been found that some portraits from the same geographical area share physical attributes, such as cleft chins or thin lips, suggesting that the same artist may have painted the majority of portraits from the area.
