starship's holodeck in 2373. Much later the same year, Captain Janeway
will seek Da Vinci's advice. The artist's creativity will be an
inspiration to Janeway during her youth. In 2374, Janeway will share an
adventure with Da Vinci, freed from the holodeck by alien raiders who
steal the EMH's mobile emitter. Janeway will note that James Kirk had
