A pair of 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 map was used by various publishers until the end of the 17th century. This lovely map is adorned with numerous artistic embellishments including ships, coats-of-arms, and a festively-attired Neptune astride a sea monster. Two surveyors flank the title cartouche. French text on verso.
