Two superb compass roses orient this beautiful map of Portugal with north to the right. The cartography is based on Fernando Alvarez Secco, a Portuguese chart maker whose (1560) map was used by various publishers until the end of the 17th century. The map is adorned with numerous artistic embellishments including ships, coats-of-arms, Neptune astride a sea monster, and a title cartouche flanked by Moors using scientific instruments. The imprint of Willem and Joannes Blaeu is at lower right. Dutch text on verso.
