Book excerpt: New things are forgotten old things - this rediscovery of the past is especially important in horsemanship and equestrian sports. Despite advances in sciences and technology, the physiologies and psychologies of the two principal agents, the equid and the human, have undergone relatively few changes since horse domestication. The studies collected in this volume outline such essential and recurring challenges in equestrianism as gender issues, equine identification, the use of hyperflexion and groundwork in training, as well as many others, from prehistory to this day.
