It is a very important book for European cartography. This volume is composed of the different parts of the previous editions of Gerard Mercator’s Atlases, bought by Gerardus Mercator junior and the publisher Hondius, with the aim of realizing a new edition, which will be published in 1613. It is the fourth edition and contains 150 maps divided into different sections: the first eight sections represent Europe, whereas the ninth one portrays the other continents known at that time. The frontispiece, remarkable from an aesthetic point of view, contains the printer marks of the publisher Hondius. The volume also contains the double portrait of  Gerard Mercator and Hondius.
