Cornelius van Wytfliet (1555 - 1597) was a Flemish cartographer and engraver active in the second half of the 16th century. Little unfortunately is known of Wytfliet's life or education. He seems to have been employed as secretary to the Council of Brabant, essentially the supreme court of the Duchy of Brabant. In cartographic circles Wytfliet is best known for his publication in 1597 of Descriptionis Ptolemaicae Augmentum, the first atlas dedicated exclusively to the America's. Wytfliet imaged the atlas as a supplement to classical Ptolemaic geographic, which traditionally accounted only for Europe, Africa, and Asia. The 19 maps contained within the Descriptionis Ptolemaicae Augmentum are some of the earliest specific maps detailed various parts of the Americas. More by this mapmaker...

Nicolò Zeno the Younger (1515–1565) was a Venetian Senator and author. He was the son of a literary man and a family powerful in Venetian politics, and was reputedly educated in science and the humanities. He was a successful hydraulic engineer, a most important field in so inundated a city as Venice. Able though he may have been, his early entrance to politics at the age of 23 was made possible via payments of 100 ducats to the Council of Ten. Following Venice's disastrous 1537-1540 war with the Ottoman Empire, Zeno wrote and published an unpublished history of the conflict notable for its invective against proponents of the war.

Zeno is mainly remembered for his 1558 publication of a map and series of letters which he claimed to have discovered in a storeroom of the family's home in Venice, purporting to describe a fourteenth century voyage by his ancestors, Nicolò and Antonio Zeno, to the north Atlantic and even to North America. Zeno's position as Senator would have discouraged question of his honesty in Venice, certainly, and the inclusion of his map in Ruscelli's successful 1561 edition of Ptolemy ensured the spread of his geographical ideas. And indeed, Zeno's map was widely accepted for over a century, influencing the maps of Ortelius, Mercator, Blaeu and others, until research (in particular that of Frederic W. Lucas, in 1898) identified both the cartographic and textual sources Zeno employed in concocting his report, demolishing its credibility. Learn More...
