Final answer:
Horses in Mesopotamia were symbols of kingly power and military strength, often depicted in art and stories like that of Bahram Gur to signify noble warriors and rulers.
Step-by-step explanation:
In Mesopotamia, horses were indeed associated with kingly power and the royalty's military strength. Many Mesopotamian rulers utilized horses, not only for their mobility in warfare but also as symbols of power. The significance of horses is highlighted through the historical records and artistic depictions of the time, illustrating heroes, kings, and hunters on horseback, often in a position of victory over adversaries. For instance, the scene of Bahram Gur, who defeats the Karg whilst mounted on a horse, serves dual purposes, representing both the tale's Persian roots and the Mongol appreciation for horsemanship and its association with noble warriors. Local artistic traditions in Persia, which became part of the wider Mesopotamian sphere, frequently showcased such imagery to signify regal dominance and prowess.
