Brushstroke-mapping AI reopens a centuries-old mystery about one of El Greco's masterpieces

Spanish Renaissance master El Greco is often considered one of the greatest painters of all time, and many of his artworks are displayed in galleries around the world. His painting The Baptism of Christ is generally believed by art historians to have been unfinished at the time of his death in 1614 and completed by his son, Jorge Manuel. But new research using AI suggests that the artist may have played more of a role in completing the work than previously thought.
