First published in Turquet de Mayerne’s ‘Discours Sur La Carte Universelle’, with the title ‘La Nouvelle Maniere de Representer le 

 Terrestre’, in 1648. This second edition differs from the first in many ways, including the removal of the title, the inclusion of de Fer’s imprint, and the naming and altering of the personifications of the seasons in each spandrel.

In his book, Turquet de Mayerne illustrates a number of different map projections by Gemma Frisius, Pieter van den Keere, 

, and Guillaume Postel. The current map illustrates a projection that was his own invention, showing the entire world in one circle with inevitable distortions to the areas at the extreme radii. The geographical outline is simplified, with the borders of various countries shown, but only a few place names. Around the map are panels of text and personifications of the seasons. The five most common azimuthal (also known as Zenithal) projections are the Stereographic projection, the Orthographic projection, the Lambert azimuthal equal-area projection, the Gnomonic projection, and the azimuthal equidistant or Postel projection, so named after Guillaume Postel's 1581 northern hemisphere map.

Most importantly, the map includes the addition of a number of place names and new islands not shown in the first edition, including ‘Nouvelle Hollande’ in the Southern Continent, where only the word ‘Beach’ had appeared before. 

 (c.1550–1618) was a Huguenot historian and political theorist, whose works included, in addition to cartographic output, a general history of Spain, theological essays, treatises on the role of science, and a philosophical tract on different forms of government. He is better known, however, as the father of the famous physician Theodore Turquet de Mayerne (1573–1655) who treated kings of France and England and advanced the theories of Paracelsus. 

This unusual world map is on a north polar Postel azimuthal projection, showing equidistant, concentric circles of latitude. It was finely engraved over two pages on copperplate and published by
