Second edition in French, enlarged to include American material derived from the Spanish edition (Antwerp, 1575), without the two separate diagrams affixed to 2B4v, as usual. Apianus' popular geographical and astronomical treatise, in the enlarged and modified version of his student, the globe- and instrument-maker Gemma Frisius, first published in 1529 and further enlarged in 1530. Gemma's most important contribution is the chapter which contains the earliest description of triangulation as a means of accurate surveying and mapping.
