In the Romano-Germanic Museum in Cologne (Diergardt collection) there is a combat knife originating from Cimmerian Bosporos. Its hilt is decorated with a bronze image of eagle’s head. The purpose of this publication is to call attention to this artifact almost not known to Eastern European archaeologists. The handles of swords decorated with eagle’s heads from the Roman Period are well known primarily from iconographic data. Noteworthy is the image on a silver bowl from Avignon (the so-called “Briseis Cup”) dated to the fourth century. It depicts a weapon with a rather short blade and a U-shaped chape; all these features resemble the Bosporan combat knife. In the Late Roman Period, swords with eagle-headed hilts were well represented in the images of the persons of status, probably indicating their prominent role of a symbol of power. Generally, eagle is well represented among the symbols of power of the Late Empire, for example, on consular rods or shields with the emblems of military units mentioned in the Notitia Dignitatum. In the Late Roman Period, sword hilts featuring bird’s head also occurred outside the Empire. This is evidenced by the image of the Sassanian Shah Shapur II on a plate from Turusheva. In the “chieftain” culture of the Eastern and Central European Barbaricum and the Northern Black Sea Area from the Great Migration Period, the inlaid patterns showing eagle or bird’s heads is well known on weapons, including swords and horse trappings. In the Barbaricum, there probably appeared the well-known phenomenon of imitatio imperii.
