*In the 16th century the astrolabe reached the peak of its popularity.
The Spanish astronomer and mathematician Juan de Rojas presented to the European public the Orthographic Projection (1550).
This projection was successfully applied in a new type of astrolabe that offered remarkable advantages over its predecessors because it could be used in any latitude.

*From the Greek “star searcher” the astrolabe was introduced in Europe by the Arabs.
