The whole thing seems no more believable than the proported Egyptian
settlement of Australia. As Denis Gojak pointed out all manner of objects
have been transported around the globe by collectors and then accidentally
discarded causing great stirs in the pseudo-archaeological community always
eager to "prove" established history wrong. ( for example they frequently
claim that Captain Cook didn't discover Australia a point with which the
Aboriginal community is in total agreement!).
