The nautical astrolabe is not an astrolabe in the strict sense, being more of an inclinometer with alidade capable of measuring vertical angles. It was an instrument widely used by navigators during the 16th and 17th centuries to find the latitude of the ship, by observing the position of the stars at a certain time of the day. The first date of its first description was made in the year 1295, by Mallorquín astronomer Ramon Llull, however we owe the first rigorous and scientific study to the Spanish cosmographer specialized in navigation: Martín Cortés de Albacar, who in 1551 published in his ” Art of Navigation” a complete study on this instrument. It is composed of a perforated metal disc, in order to allow the wind to pass through it so that the astrolabe could remain as vertical as possible to carry out measurements with greater precision.

The one that Punto Vernal reproduces is a replica of the one found on a Spanish ship sunk off the coast of England and belonging to the so-called “Invincible Armada.” It is made of metal bathed in old brass and is accompanied by a manual with its history and instructions. It comes in a beautiful gift box.
