Last summer, a team of scholars and scientists called the Lazarus Project started examining a map of the world made in Italy in 1491. It’s called the Martellus Map, named after its maker, Henricus Martellus Germanus, a German living in Florence. Martellus filled his map of the world with descriptions of what, then, were far-off places like Africa and Asia. Those words faded away centuries ago, but this team believed they could use an imaging technique to read them. What they’ve found may give historians cause to look at European history a little differently.
