No, 180 degrees wouldn’t change things. That must be why I read it as 90 degrees.
Wait. If Cumae is "a few miles south of Naples", [as Siankan said], how could it be "in the center of Europe"? I don’t understand.
It’s in the center west-to-east, but it’s in the far south. That’s why I thought you must mean 90 degrees.
Well, bottom middle.
