Resumen de Circulation and Contacts in Sixteenth Century New Cartography: Spain, Portugal and Italy
Cartographic information was highly coveted in sixteenth century Europe, especially when it came from Portugal or Spain. Maps and nautical charts produced in the Iberian Peninsula were loaded with sensitive information about the new lands discovered, which made them the object of desire of rival or curious powers. Faced with this, the Spanish and Portuguese institutions tried to limit the excessive dispersion of cartographic material, using several legislative instruments. In theory, the circulation of cartographic information beyond Iberian imperial boundaries was strictly controlled, so the possibility of leakages or exchanges seemed very unlikely. In practice, both leaks and contact occurred constantly. The objective of this article is to illustrate this idea from the identification and analysis of concrete historical events in which the circulation of cartographic information took place. The chronological framework chosen is the sixteenth century, with Spain, Portugal and Italy as the main sites.
