Although the impressum of this map suggests a cooperative edition of <a href="https://en.wikipedia.org/wiki/Willem_Blaeu" class="extiw" title="en:Willem Blaeu">Willem Jansz. Blaeu</a> (1571-1638) and <a href="https://en.wikipedia.org/wiki/Joan_Blaeu" class="extiw" title="en:Joan Blaeu">Joan Blaeu</a> (1598-1673), it seems that this map was originally published in 1640 in the the third volume of the Atlas Novus by Joan and his brother <a href="https://en.wikipedia.org/wiki/Cornelius_Blaeu" class="extiw" title="en:Cornelius Blaeu">Cornelius Blaeu</a> (c. 1610-1642). As most of the maps of Italy, this map was copied by Blaeu after an example from the map book <i>Italia</i> by the Italian cartographer <a href="https://en.wikipedia.org/wiki/Giovanni_Antonio_Magini" class="extiw" title="en:Giovanni Antonio Magini">Giovanni Antonio Magini</a> (1555-1617).
