Although Leonardo da Vinci never finished this 1481-82 painting (his services were wanted by the Duke of Milan), it is considered one of his more important early works. Adoration is especially intriguing because it has an earlier drawing under the visible artwork; to Dan Brown, this evidences a conspiracy to hide the "original" drawing, which he believes might contain clues to information that would damage the church. In reality, leaving the visible painting was not done "to subvert Da Vinci's true intention" (DVC, 169). Resistance to restoring Adoration to its "hidden" underdrawing was about leaving it in its rightful state as Leonardo left it.
