The Adoration of the Magi was an unfinished painting by Leonardo da Vinci that depicted Mary and her child Jesus Christ being lavished by gifts by the Biblical Magi, (also known as the Three Kings).
In 2374, this picture was used as an example by Kathryn Janeway to remind the Da Vinci-hologram how often he had given up and that he should not do the same with his gliders. (VOY: "Concerning Flight")
