Hannibal Lecter MD

The horse in dr. Lecter’s office is a Chunar Horse Statue. The statue is reproduced after a carved original in the genre of a Tang Dynasty Horse, but is stylized after artwork from from the ancient town of Chunarin in India. 

And there are actually two other things it can reference - ‘the broken pony’ (it’s not acctually broken, but has holes) as Will is starting to crumble and the Troyan horse as Jack willingly pulled Hannibal inside the FBI investigations.
