A tomb in Egypt, on the sea coast, is being investigated by Egyptian archaeologist Zahi Hawass, who claims it is the final resting place of Cleopatra and her main squeeze, Mark Antony. One of the pieces of evidence used to make this claim is a mask with a cleft chin, just like Richard Burton’s.
It seems that most non-Egyptian archaeologists are claiming that this is incredibly unlikely. Most of the actual relevant evidence that would address the likelihood has not been examined by anyone, so I won’t take this disbelief any more seriously that I’m taking the claim.
Details can be found here in what is actually a pretty funny news report.
