The relationship between horses and humans is an ancient, profound and complex one. For millennia horses provided the strength and speed that humans lacked. How we travelled, farmed and fought was dictated by the needs of this extraordinary animal. And then, suddenly, in the 20th century the links were broken and the millions of horses that shared our existence almost vanished, eking out a marginal existence on race-tracks and pony clubs. 'Farewell to the Horse' is an engaging, brilliantly written and moving discussion of what horses once meant to us.
