Thousands of years before Stubbs was painting, the horse had been visualized in the Palaeolithic cave images which adorn the walls of the the Lascaux Caves in south west France.
"It's the most paintable subject in animal world," renowned artist Terence J. Gilbert told CNN.
"The horse is such a beautiful animal to and is an inspiration to all.
"With a race horse, it has so many variations in form, in color and style."
Gilbert began his work as an illustrator before moving onto painting. As a young boy, he would accompany his father to race tracks across southern England and it was there that his love affair with horses began.
Since then, he has painted some of the most famous and iconic horses in history such as Denman, Kauto Star and Yeats, while he was also recently commissioned to paint Queen Elizabeth II during her visit to Coolmore Stables in Ireland.
"A classic painting can take anything from two to three weeks with Gilbert currently working on a painting of the Queen's Ascot Gold Cup winner Estimate.
"It is the movement of the horse which interests me," he added.
"You paint every aspect in the way you can and you make it perfect. It's difficult to do that with a photograph.
"In a photo, you might get one part of it that looks great but another which isn't as good. With a painting, it's possible to make it all perfect."
For some, such as Michelle McCullagh, the opportunity to capture the horse during the gallop at the racecourse is one of the most fascinating aspects of her work..
"A large, lush field full of thoroughbred mares and foals basking in the sunlight is heavenly to see," she said.
"To be there, with them, drawing, adds to the very special experience. Yet there is nothing more exciting and challenging, than to be stood at the side of the gallops or at the race course, where the atmosphere is so diverse.
"There is always something for the artist -- a shining horse being washed off, walking round the paddock, jockeys jumping on, spooky, skittish horses, exhausted horses and with the fit thoroughbred, so much of the anatomy is there to see. It is excellent. I love it."
