⚠️ Disputed: the sources disagree.

What it is

Antler or bone cheekpieces with prongs and later an articulated bronze bit in the horse's mouth, joined to reins, allowing precise control of a pair of horses at a gallop. Without it, the war chariot is unmanageable.

Bit wear on Botai teeth (c. 3500 BCE) is disputed; the antler cheekpieces of Sintashta (c. 2000 BCE) are the earliest secure evidence.

What it led to

  • Fine control of the horse that turned the chariot into a weapon and, later, made cavalry possible
  • Written training manuals (the Kikkuli text, Hattusa, c. 1400 BCE), the first zootechnical literature
  • Selective breeding of chariot horses and trade in horses as a strategic good
