Explanation:
What is it?    
   
It was found at the bottom of the sea aboard an ancient Greek ship.     
   
Its seeming complexity has prompted decades of study,    
although some of its functions remained unknown.     
    
X-ray images of the device have confirmed the nature of the    
Antikythera mechanism,    
and discovered several surprising functions.     
   
The Antikythera mechanism   
has been    
discovered to be a    
mechanical computer of an accuracy thought    
impossible    
in 80 BC, when the ship that carried it    
sank.      
   
Such sophisticated technology was not thought to be developed by humanity for another   
1,000 years.   
   
Its wheels and gears create a portable    
orrery of the sky    
that predicted star and planet locations as well as    
lunar and    
solar eclipses.   
   
The    
Antikythera mechanism,    
shown above, is 33 centimeters high and therefore    
similar in size to a large book.
