The map is double-hemisphere, within an ornate strapwork frame containing an armillary sphere and compass rose. California shown as part of the mainland, there is the distinctive bulge in South America, and the kingdoms of Beach, Lucach and Maletur are shown as part of the mythical southern continent “Terra Australis”.

The map was first published in Strabo’s ‘…Geographicarum libr XVII’, with text beneath the map headed “Lectori S.P.”, and no text on the verso. In 1587 Rumold Mercator issued a reduced version of his father’s great modern world map, which had first been printed in an edition of Strabo’s “Geographia”. It was another eight years before it first appeared in a Mercator atlas, in 1595.

The present map with the four columns of text below, and no text to the verso, appeared in the 1595 first edition of Mercator’s Atlas. The map is distinguishable from the later editions of the map, which are marked by a signature letter ‘A’ to the verso.
