The shield consists of many parts. In the center is an image of Mount Ararat with Noah's Ark sitting on top of it. According to tradition, the ark is said to have finally rested on the mountain after the great flood. Ararat is considered the national symbol of Armenia and so is of significant importance to the coat of arms. Surrounding Mount Ararat are symbols of old Armenian dynasties. In the lower left portion of the shield, there are two eagles looking at each other, symbolizing the length of the Armenian territory during the reign of the Artaxiad Dynasty that ruled in the 1st century BC. In the upper left portion, there is a lion with a cross, the emblem for the Bagratuni dynasty that ruled during the Middle Ages, between 7th and 11th centuries. Under this dynasty, Armenia blossomed culturally, making its capital, Ani, one of the most important cultural, social and commercial centers of its time. Bagratuni was destroyed by the Byzantine Empire's encroachment and by Seljuk invasions in the 11th century AD. In the upper right portion, there is a two-headed eagle, the emblem of the first dynasty to reign over a Christian Armenia, the Arsacid Dynasty of Armenia. Tiridates III of Arsacid Dynasty made Armenia the first Christian nation in 301 AD. This dynasty ruled from the 1st century AD to 428 AD. In the lower right portion, there is a lion with a cross, the emblem of the Rubenid dynasty. This dynasty reigned in Armenian Kingdom of Cilicia, a state that expanded and prospered during the 12th and 13th centuries, until the Mamelukes and Turks eventually conquered it.
