For a similar bronze helmet of Sarduri II, cf., B. B. Piotrovskii, Urartu: the Kingdom of Van and its Art, London 1967, pl. 16. Comparisons can be drawn between Urartian armour decoration and the Assyrian palace reliefs of the 8th Century B.C. Piotrovskii op cit, p. 15, suggests: "The relief decoration on the shields, helmets and quivers which bear dedicatory inscriptions of urartian kings may also be classified as palace-art. their decoration frequently consists of repeated figures of lions, bulls and other creatures, which were embodiments of power. It is no accident that on the Assyrian palace reliefs, whose purpose was to display the king's exploits, he is shown hunting lions and wild bulls [...] Sometimes the animals are replaced on war-gear by rhythmical processions of alternate chariots and mounted warriors, and sometimes also by sacred trees with divinities standing on either side of them." The overall purpose of this type of decoration was to convey an impression of wealth, magnificence and power.
The representation of mythical snakes with lion heads is a recurring theme on Urartian helmets and is likely to have served as a form of magical protection against evil forces. See also, H. Born & U.
