Large circular map depicting the whole world centred on the South pole, with the North pole around its outer edge. All the landmasses are drawn in reversed form. Text in Latin, Flemish, Dutch, French, Portuguese, Spanish, English. Inscriptions include the note "Nil facilimus vilius quam sine certe indice aliorum Labores" (Nothing is easier and nothing is meaner than to speak evil of, or look askance at the work of others without definite proof). Pisani's friendship with the mathematician Francois d'Aguillon, a mathematician who wrote an important book about map projections, led to the innovative projection used for this map. Pisani wrote to Galileo Galilei that his map put “within a circle the whole of the flattened globe, something that no one has done before.”

The map is dedicated to Albert, Archduke of Austria, Duke of Burgundy.
