What is the english name for the element the romans called cuprum?

Here you go!

The Latin term, during the Roman Empire, was aes cyprium; "aes" was the generic term for copper alloys such as bronze). Cyprium means "Cyprus" or "which is from Cyprus", where so much of it was mined; it was simplified to cuprum and then eventually Anglicized as copper (Old English coper/copor).
