Excellently preserved, complete crossbow from 2,200 years ago found at Terracotta Warrior site ... Reported by news site China.org to be the most complete crossbow found to date at the site, it has a 145 centimeter (57 inch) arch and, incredibly, the bow string remains intact and measures 130 centimeters (51 inches) long. Researchers believe the string is made of animal tendon rather than fabric, which would have degraded and disappeared long ago.

The pic of the bow as found in the site is not quite as beautiful as the featured image, but it's even more interesting.
