Knight has utilised the intense blue hue and technical precision of the cyanotype to examine the evolution of the horse bit. The design and materiality of the bit is driven by function and efficacy and has evolved from earlier versions that were shaped from rope, bone and horn, dating back to Kazakhstan in 3500 BC.

In Knight's cyanotypes the joints, rings and shanks of the metal horse bit create enigmatic forms that allude to an arcane language. The bit at it’s most rudimentary is a way to communicate direction and speed, but at the more advanced equestrian levels the bit can harness the horse's energy and rhythm for the more complex dressage movements.
