@
The at sign was first put to paper in the 14th century, way before the internet! The sign has not always been a symbol for someone’s location or email address. In the 16th century in Italy, the sign was an abbreviation of the word ‘amphora’: a jug that was used as a unit of measurement. That’s why the at sign is sometimes called an amphora in different languages. In that same century, the @ was a time indication in the Netherlands. In Spain and Portugal it represented another unit of measurement: the arroba. The @ on your pc is far more than a random scribble.
