Edward, Duke of York, was a writer, his principal work being The Master of Game, written during a well-deserved spell in prison. (He is also reputed to have been a poet, though the one work I have seen attributed to him suggests he was not exactly up there with Chaucer.)
The Master of Game is a fascinating book, covering most aspects of medieval hunting in great detail. Much of it is a translation from an earlier work by Gaston Phoebus Count of Foix, but Edward did add five chapters of his own. One thing that becomes clear from Edward's writing is his regard for greyhounds. He classes them as 'fit for a knight or his lady' - in effect dogs for the nobility. Hunting was, of course, the preserve of the landed classes in the middle ages, although it was common for monks and other clergy to take part in the sport. (Monks often got in trouble for keeping unauthorised greyhounds.)
The reason I mention this is that greyhounds in our modern world are a much-abused breed, and need as much of our help as possible. If you can find it in your heart to give one a home, please do so - you will be rewarded with a loyal and loving companion, albeit one who may need to be watched while it learns not to chase cats and other small animals! Contrary to what you might think, they don't need a lot of exercise, and are more likely to wear out your sofa than your legs.
If you can't have one at home, why not sponsor one of the many rescue centres? You could do a lot worse than join me in supporting Tia Greyhound and Lurcher Rescue. They do a great job for these aristocratic animals!
