It seems unlikely that the graffiti you see around today will be of much use to the historians of the future. And, of course, we don’t know whether the street art that graces our towns and cities will even survive for centuries to come. That’s not an impossible prospect, though, if a find made in Italy in 2018 is anything to go by. And after uncovering the graffiti, archaeologists at the location noticed that the daubings appeared to overturn what we thought we knew about the eruption in Pompeii.
