Obvious effort went into the development of the map of Africa. The geography in the Janssonius map borrows some aspects from Jodocus Hondius’ 1606 folio map of Africa and Hondius’ reduced-size map of 1607, though Janssonius seems to rely more on Willem Blaeu’s folio map of 1617 and his wall map of 1608. There are numerous additional placenames throughout this map, when compared to the slightly larger 1607 Hondius map. The configuration of the interior river systems closely follows Blaeu’s wall map of 1608.

Some time after Janssonius’ death in 1664, the copperplates were acquired by Pieter van der Aa.  Van der Aa completely reworked the title cartouche, inserted a compass rose, and erased the name of the original engraver, Abraham Goos.  The map of Africa was included Van der Aa’s extremely rare atlas. Part One of the atlas was called Nouveau Petit Atlas and Parts Two through Nine were called the L’Atlas soulagé de son gros & pesant fardeau. The atlas was published in Leiden in c.1714. In this edition, the Africa map has no text on the verso. The map of Africa appeared both in Part One and Part Nine of the atlas.
