Ancient early roman bronze bell that's still works.
Perfect example of a early roman Bell sometimes none to be used by soldiers as a way to scare their enemy. Sounds strange but just think of you first of never saw a Roman. Much less 50 thousand of them ready to take evening you held dear and ever knew. The bells would be the least of your problems but these have stood the test of time and still actually make a beautiful sound. Museum quality and very rare to find whole.
