This attractive little map of Portugal was published in Amsterdam by Petrus Bertius. The work it comes from is a revised edition of Barent Langenes' "Caert Thresoor". The maps were mainly newly engraved by Jodocus Hondius, this one being by Salomon Rogiers. Van der Krogt, P. (Atlantes) 6281:342; Shirley "Atlases in the BL" T.Bert 2a.
