A manual on horseman ship and horse care by Thomas de Gray (Esquire) that was published and republished throughout the century, though it often seemed to be a book that invited comment rather than acceptance. Extant copies often have annotations written in the margin, not always in agreement with Mr de Gray. Much like cars today, everyone had their own opinion about horses and how to look after them in the 17th century. This is the frontispiece of the 1639 edition featuring the King in classic dressage pose on a rather small-headed horse. Charles is wearing a smallish brimmed felt hat, a doublet with slashed sleeves, breeches with ribbons at the knee, a nice pair of boots and a lace falling band.
