The Thread of the Moth

~4,300 years ago

History · Bronze Age · Holocene · Northgrippian

Somewhere in Neolithic China, someone learned to unwind the cocoon of a moth into a single filament hundreds of metres long, and to keep the insect as livestock: the silkworm became the only fully domesticated invertebrate of antiquity. Woven silk survives from the third millennium BCE; Shang oracle bones already inscribe the words for silkworm and silk. And microscopy has found wild-moth silk in Indus ornaments of the same era: China's monopoly was on the domesticated thread, not the idea.

Why it matters

Silk became antiquity's most valuable portable good, the fibre that named the roads across Eurasia and paid for empires; its secret was guarded like a weapon for two millennia. It is also domestication at its most intimate, a moth remade until it could no longer fly, for the sake of a thread. The luxury trade it created was globalization's silk-thin prototype.

Dating & uncertainty

Actual silk textiles survive from the Chinese Neolithic, at Qianshanyang, in the later third millennium BCE, with sericulture presumably older; Shang oracle bones write of silkworms and silk by the second millennium. The surprise is elsewhere: silk fibres from wild moths, dated about 2450 to 2000 BCE, have turned up in Indus civilization ornaments, questioning the exclusivity of the Chinese story.
