Roman Bronze Eagle Head on custom stand, probably from a small knife. Circa 2nd - 3rd Century C.E. 1" high without stand. Small loss between eyes but otherwise in excellent condition. Ex: Bonham's, London. The eagle was extremely important to the Roman military, beyond merely being a symbol of a legion. A lost standard was considered an extremely grave occurrence, and the Roman military often went to great lengths to both protect a standard and to recover it if lost; for example, see the aftermath of the Battle of the Teutoburg Forest, where the Romans spent decades attempting to recover the lost standards of three legions.
