Johannes Goropius Becanus was a man who lived a long time ago and was interested in studying languages. He believed that all languages in the world actually came from one language that was spoken a long time ago by Adam and Eve. He even wrote a book about it called "Origines Antwerpianae" and became famous for his ideas.
However, many people today do not agree with Johannes Goropius Becanus' theory. They believe that languages developed in different parts of the world over time and were not all based on one original language. So while he was a smart man who studied languages, not everyone agrees with his ideas about the origins of languages.
