Trace a Network Rather Than One Long Road

The Silk Roads were many connections

The Silk Roads is a modern name for changing overland and maritime connections across Eurasia and beyond. Silk was one cargo among many, including metals, textiles, spices, and religious objects. Cities and oases supplied water, food, storage, and markets. Political borders, conflict, and environmental change could redirect traffic. A map should therefore identify a period and distinguish an evidenced connection from a possible one, rather than drawing a single timeless highway.
