There was also the Cosmográfo - cronista mayor de las Indias in Madrid at the Consejo Real y Supremo de las Indias, the map of Spanish South and Central America created. Zamerano was replaced a few years as Piloto Mayor Andrés García de Céspedes, as he kept his knowledge too much of the Consejo de las Indias opinion for himself and did not share. In 1613 he went into retirement.

He published books on navigation, calendar and mathematics. He was in his field at the time of Philip II as one of the greatest scholars. For astronomy and calendar calculations used the Prutenischen panels, based on ideas of Nicolaus Copernicus.

In 1576 he published in Seville the first Spanish ( Castilian ) translation of the Elements of Euclid, but only the first six books. He translated from the Greek, closely followed the text without their own additions, or omissions and was the other contemporary Renaissance translations into modern languages ​​, which were often quite freely, far superior. The book was written as a textbook for the navigation school in Seville.
