ネズ・パース
Artwork depicting prehistoric horses with leopard spotting exists in prehistoric cave paintings in Europe. Images of domesticated horses with leopard spotting patterns appeared in artwork from Ancient Greece and Han dynasty China through the early modern period. In North America, the Nez Perce people of what today is the United States Pacific Northwest developed the original American breed. Settlers once referred to these spotted horses as the "Palouse horse", possibly after the Palouse River, which ran through the heart of Nez Perce country. Gradually, the name evolved into "Appaloosa".
