I don’t know why I continue to be surprised by these kinds of things, but sometimes you don’t realize something that you’ve been told all your life is wrong until you’ve pulled it out of the drawer and given it a good shaking out.
Imagine I built a time machine and traveled back to the 1480s to give John Cabot a handshake and a thumbs-up. I’ve been informed all of my life that this fellow was the man who discovered the nation of my birth, Canada, but if I were to walk up to him on the street and say “Hey, John, good one,” he’d likely have no idea who I was even talking to.
Zuan Chabotto, on the other hand, would have no problem giving me a fist bump.
In Italy he is known today as Giovanni Caboto, in Spain as Juan Caboto and in England as John Cabot.
As for the way he described himself, only one set of documents has been found bearing his signature. These are Venetian testamentary documents of 1484, on which he signed himself as “Zuan Chabotto”, Zuan being a form of John typical to Venice. – wikipedia
