Archaeologists discovered flax fiber cords in a western Asian cave that date from 32,000 to 26,000 years ago. In a cave at Lascaux, France fossilized remains of a “two-ply laid rope of about 7 mm diameter” were dated to about 15,000 BCE. Hemp twine was used from about 8,000 BCE. By 1,000 BCE hemp rope and twine was used by most civilizations. From 500 BCE to 1900 AD almost all rope and twine used in sailing ships was made from hemp. For example, the USS Constitution used hemp for its rigging lines. Sea bags and other common goods used help cordage or twine.
