This sentence found in Colleen McCullough’s The Thorn Birds (1977) has been throwing me off:
His nose was magnificent, a true Roman nose which must have puzzled his Irish confreres, but Ireland has ever been a shipwreck coast.
The last clause sounds like an incomprehensible non-sequitur. And is “ever” even compatible with “but” in this context? Shouldn’t there be a negative of some sort? I found no idiomatic usage whatsoever associated with “shipwreck coast.” Please help!
