On Thursday 26th November, Professor Robert Hannah (University of  
Otago, New Zealand) will reveal to us the inner workings of the  
Antikythera Mechanism, the most significant scientific instrument to  
have survived from antiquity.

The Mechanism was recovered in 1901 from a 1st century BC shipwreck  
off the cost of the Greek Island of Antikythera.   The corroded  
bronze plates of over 30 interlocking gears have been subjected to  
scientific analysis (including radiation scans).

Many models have been constructed in attempts to unravel the workings  
and to help determine what this time-tracking device might have been  
used for. Our current understanding is that it is a predictor of  
astronomical positions.

Allan Bromley and Frank Percival’s model of the Antikythera Mechanism  
is on display at the Nicholson Museum in the exhibition “The sky’s  
the limit: Astronomy in Antiquity”.
