An antique cast bronze painted coat of arms of Montenegro featuring a two-headed eagle and a lion passant on the inescutcheon is as a sign of episcopal authority. The layout of the Montenegrin coat of arms is inspired by that of the Russian Empire, with which the ruling House of Petrovic-Njegos had close dynastic and political ties in the 19th century when the coat of arms was first adopted in its present form. Dates to the 19th century. Antique Heraldic Collectibles.
