On the earliest printed portolano (Venice, 1490)

In November 1490, Bernardino Rizo da Novara issued the earliest printed anonymous portolano. Several months later, a print privilege was issued at the request of Andrea Badoer, a merchant. With the support of a newly published database of Venetian privileges, it is contended that Badoer sponsored the print and possibly provided the text of the portolano.
