An Ancient Case of Horner Syndrome?

The National Archeological Museum in Athens houses this philosopher's head (Fig. 1). The artifact was retrieved in 1901 from the sea off the coast of the Greek Island of Antikythera. Also found in the same cargo, believed to have been shipped to Rome, were other parts of the statue, other relics, and the world-famous 'Antikythera mechanism,' an ancient Greek analogue computer used to predict astronomical events. The creator of the head sculpture is unknown, and no previous description of it has been found in literature; it could date back to 240 BCE circa.
