BRITISH APPALOOSA ORIGINS:
In England, spotted horses can be found illustrating early manuscripts bearing either saints or nobles upon their backs. Charles II had a strangely marked grey with red on his rump named 'Bloody Buttocks'. In the 18th and 19th centuries, one or two spotted horses appeared in English paintings like John Wooton's Lady Conway's Spanish Jennet now in possession of Lord Hertford at Ragley Hall in Warwickshire as pictured below by kind permission.
Although it is claimed there were indigenous spotted horses in Britain, it is likely that these came originally from the continent. This is thought to be due to the French Cave paintings stated earlier, which geographically speaking, is a close neighbour.
Up to recent evidence to suggest that spotting patterns have arisen independently anywhere else in the world, it was a viable assumption that the cave dwellers in France were painting something new. As the spread from Southern Europe continued, the spotted horses interbred with native stock and eventually took on conformation appropriate to their new homes.
