βίσων
bisōn
Ancient Greek
“The Greeks borrowed a Germanic word for the European wild ox, the Romans passed it along, and Americans applied it to a different animal on a different continent.”
The Ancient Greek bisōn (βίσων) appears in Aristotle's Historia Animalium around 343 BCE. He described it as a wild ox found in the forests of Paeonia (modern North Macedonia). The word was not Greek — Aristotle seems to have borrowed it from a Thracian or Germanic source. The Proto-Germanic *wisundaz, meaning 'wild ox,' is the likely ancestor.
Latin adopted bison directly from Greek. Pliny the Elder mentioned the animal in his Natural History around 77 CE, noting its shaggy mane and fearsome temper. The European bison — the wisent — roamed the forests of Germany, Poland, and Lithuania. Medieval hunters prized it. Medieval scribes kept the Latin name.
When Spanish explorers reached the Great Plains in the 1530s, they encountered vast herds of a large, shaggy bovine. They called it cibola. But English-speaking settlers, arriving later, reached for the classical word: bison. The American bison (Bison bison) is a different species from the European wisent (Bison bonasus), but the name transferred without hesitation.
By 1890, commercial hunting had reduced the American bison population from roughly 30 million to fewer than 1,000. The near-extinction became one of the first conservation causes in American history. Yellowstone National Park's herd, never fully eradicated, became the genetic foundation for recovery. Today about 500,000 bison live in North America. The word survived. So, barely, did the animal.

Americans still argue about whether to say 'bison' or 'buffalo.' Technically, the American animal is Bison bison, not a buffalo at all — true buffalo are African and Asian. But 'buffalo' is older in American English, embedded in place names from Buffalo, New York, to Buffalo Gap, Texas. Language does not care about taxonomy.
The near-extinction and recovery of the bison is now a standard conservation parable. From 30 million to 1,000 to 500,000. The animal that was nearly erased from the plains now appears on the U.S. nickel. Survival is not always graceful, but it counts.
