7. Leonardo da Vinci’s anatomical drawings on display
The Queen’s Gallery at Buckingham Palace has mounted what it says is the largest-ever display of Leonardo da Vinci’s anatomical drawings, which are a part of the Royal Collection. Da Vinci’s extensive drawings were unpublished during his lifetime and essentially lost to the world for more than 400 years after his death. The Royal Collection says the sketches are among its greatest treasures.
