Copper is the chemical element of atomic number 29. Its symbol is Cu.
In all likelihood, copper is the metal that mankind has been using for a long time: copper objects dating back to 8,700 BC were found. The name comes from Latin spoken aramen (word already attested in 950) for late aeramen, a derivative of the Latin word aes meaning "copper" or "bronze", names preserved in other languages of indo-european origin.
Only later it is replaced (Pliny) by the word cuprum, which derives the chemical symbol of the element. In Roman times most of the copper was extracted from the island of Cyprus, a reality which was underlined with the term aes Cyprium, "copper or bronze of Cyprus".
In fact, in the Roman era there was no difference between pure copper and bronze, its most important alloy obtained with the addition of tin.
