The Tea-Horse Trade was also revived, reflecting the Ming state’s persistent effort to secure reliable cavalry resources, as well as the animal’s crucial role in facilitating exchanges.

In the Western world, horses also played a connective role. From the Persian Empire to Rome, mounted couriers, cavalry and traders depended on them to bind together territories spanning thousands of kilometers.

During the medieval period, between the 8th and 13th centuries, equestrian cultures in West and Central Asia further refined breeding, veterinary knowledge and riding techniques, which later spread to Europe through trade and contact.

Technology associated with horses traveled in both directions as well.

According to Li Yongping, a researcher from the Gansu Provincial Museum in Lanzhou city, Northwest China’s Gansu province, archaeological and historical evidence suggests that chariot technology reached China from the Western Eurasian steppe and was adopted during the Shang Dynasty (c. 16th century-11th century BC).

Many centuries later, the innovation of the single-metal stirrup — widely believed to have originated in East Asia around the third or fourth century — spread westward through the steppe, eventually transforming warfare and mobility in Byzantine and medieval Europe.

“Across these networks of exchange, the horse consistently occupied the boundary between cultures — a living agent that crossed borders and rendered them permeable. Even today, it recalls a world in which distance was measured in days of riding rather than hours of flight, and in which movement depended on endurance, trust and mutual reliance,” says Li.

From this shared history of movement and encounter emerged a deeper, more enduring role. Across both worlds, the horse came to serve as a mirror of human aspiration.

Whether rearing beneath an emperor or standing quietly in a scholar’s painting, it carries the same lingering question: how should strength be borne, and to what end?
