What have the Romans ever done for us?

Examples of key rings have been found as far back as Roman times when they were worn as an item of jewellery as well as having a practical purpose. This was a combination of a ring and a small key, hence the name 'keyring'! Since Romans wore togas with no pockets, the only option for keeping small objects from getting lost were to keep them in a purse or wear them on one's person. Today the keyring has evolved to become a fashion accessory in all shapes and sizes.
