Identification of different iconographic features has allowed modern scholars to argue cases for several possible candidates responsible for the commissioning and representation within Plate LIII. Due to minor characteristically different chariots and artistic techniques, scholars have made widely divergent claims about the origins of the wall paintings that were found at Til-Barsip. In this paper I contend that one vital iconographic factor has been overlooked by modern scholarship and that it is the key to proving that a specific Assyrian king was responsible for Plate LIII. It is concluded that the Assyrian king depicted in the Til-Barsip wall painting was left-handed and by a process of elimination can be none other than Esarhaddon.
