It is very likely that the individual maps prepared for the new edition of the ‘Speculum’ may have been issued separately without text, prior to the publication of the atlas. Although the eventual sales of 

's work were less than ideal, the atlas was evidently held in high regard, with several contemporaries citing its importance alongside the atlases of 

. Few examples of either edition of the 'Speculum' have survived, making the maps within a rarity.

The Northern Hemisphere presents the continents of Europe, Asia, Africa and North America in great detail. The cartography is generally accurate, most major cities are named, and topography is illustrated. India, however, is shaped quite irregularly, and several of the south-east Asian islands are incorrect, either in name or in location. Similarly, while the American coast is well-drawn, the continent lacks many details, having not yet been thoroughly explored and mapped. It also contains a few mythical cities, such as Quivira and Civola. 

Similarly, although the land shown around the circumference of the Southern Hemisphere is generally accurate, the second half of the map is dominated by the erroneous ‘Terra Australis Incognita’. As a result of the Polar Hemisphere projection, the land closest to the Equator has been compressed; consequently, there appears to be little space between Asia and America, with Japan equidistant between the two continents.

 (1509–1591), was a Netherlandish cartographer, engraver, and publisher who lived and worked in Antwerp. In 1547, de Jode was admitted to the Guild of Saint Luke and began his work as a publisher. He frequently printed the works of other cartographers, including Giacomo Gastaldi's world map in 1555, Jacob van Deventer's map of the Duchy of Brabant in 1558, and Ortelius's eight-sheet world map in 1564. He is best known for an atlas titled the ‘Speculum Orbis Terrae’ first published in 1578. 

This is one of the two spectacular new world maps prepared by Gerard’s de Jode son. Cornelis de Jode (1568–1600). It is one of a very few double-hemisphere maps drawn on a polar projection, a style used rarely by sixteenth-century cartographers. Drawing on a range of sources, particularly Guillaume Postel’s 1581 ‘Polo Aptata Nova 

a Universi’ and an anonymous set of gores from c. 1587, de Jode’s map demonstrates not only the wealth of geographical insight generated by early European exploration but also the limits of contemporary knowledge.

It is one of only a few double-hemisphere maps drawn on a polar projection. Even the windheads are depicted from above. The map has been beautifully engraved and features bright, contemporary colour.

This map appeared in the last edition of the 'Speculum Orbis Terrae’. It was designed to compete with 

' now dominant atlas. Due most likely to Ortelius' efforts to suppress his rival, de Jode's work, it sold in relatively small numbers. However, it was nonetheless greatly admired.

’s atlas 'Speculum Orbis Terrae', first published in 1578 with text by Daniel Cellarius. It was designed to compete with 

' atlas, 'Theatrum Orbis Terrarum', which had been published eight years earlier. Ortelius had used his influence to disrupt de Jode's application for a royal privilege. By the time this was finally granted, seven years after the publication of the 'Theatrum', Ortelius's work had become so popular that de Jode's atlas did not sell well, despite the accuracy and clarity of his maps.

It is one of a very few double-hemisphere maps drawn on a polar projection, and a very fine example with superb contemporary hand-colour.
