Question of the Day?
Reckon you're right about the first two infamous 'can't-bes', but I'll bet that most UK/Commonwealth members would have also instantly recognised the third😉 Remnants of which were found off the south coast of UK and preserved at tremendous effort and cost!
This is reflected in the jump of correct answers from the UK.
Anyway, a simple process of elimination should suffice; northern European/US names in Greece in 4BC? I don't think so😉
Cheers, Doug 😎
