If 160 BC is the Roman era, then sure we agree. But it straddles the Bronze Age and in fact it's almost definite that the mechanism discovered was merely one in a long line of such mechanisms and that first invention dated to Archimedes (c.272-205 BC). In any event, it's not Roman and thus the post should have read "Roman era." To call it a Roman device is simply inaccurate in any context.
You're right, I should have used the term "era" in there. ust to be clear though; 160 bc was certainly the Roman era. The city of Rome was founded in the 700's BCE. The Punic wars were fought between 264–146 BCE. Rome conquered Greece in 146 BC. Rome dominated the seas for generations before the mechanism was made.
