5. This is the original harness derived from the Roman design. Because of the placement of the top strap and that the pull lines were at the top, the harness had the unfortunate habit of choking the horse if it pulled too hard. The next-gen harness (the breast harness) was better but the breast strap could still ride up and choke the horse.

6. So along comes the horse collar. It fits around the horse’s head with the pull lines at the sides. This puts the pulling pressure on the shoulders and breast of the horse, and off its neck. The horse can now be used as a good farm implement.
