It can be said that EAA/T began many centuries ago, when humans first realized the importance of their relationship with horses. The horse was drawn into every aspect of their life, and became relied upon for power, performance, pleasure, food and health. Emerging from the time of images, myths and magic, the horse became known as an excellent exerciser. Since Hippocrates, doctors have suggested the horse be used to exercise people and raise their spirts. Some even suggested it was good for digestion, while others, found the movement to resemble that of humans, and must be good for all life activities.
Today, EAA/T was developed through two models – the German and British model, and then shortly afterwards came the American Model.
