Vicente Mut Armengol

Vicente Mut i Armengol (25 October 1614 – 27 April 1687) was a Mallorcan astronomer, engineer, historian, mathematician and soldier. One of the most distinguished Spanish astronomers of the seventeenth century, Mut studied the Pleiades, the diameter of the Sun, and the determination of the meridians.

Biography The son of a cavalry officer, he studied humanities at the Jesuit college of Montesión at Palma. In 1629 he entered the Society of Jesus, but soon left the order. He received his doctorate in law from the Estudi General of Palma, Majorca. An expert on military engineering, he joined the Mallorcan militia and was promoted to the rank of sergeant major. He directed various fortification works in several strategic areas of the Balearic Islands and took part in repairing the walls of Palma. He served with distinction in the Reapers' War. In 1641 he was appointed General Chronicler of the Kingdom of Majorca, and in 1651 he was elected deputy to the Cortes. Later in his life Mut became town councillor in Palma and administrator of the same city.

Mut was an esteemed practical astronomer. In the 1640s, he began an epistolary relation with the German polymath Athanasius Kircher and the Italian astronomer Giovanni Battista Riccioli, becoming one of Riccioli's closest collaborators. Mut carried out several observations, many of which have been recorded by Riccioli in the Almagestum Novum in the Astronomia Reformata and in the Geographia Reformata.

Mut died in Palma on 27 April 1687, aged 72. The crater Mutus on the Moon is named in his honor.

Works Map of the island of Majorca delineated by Vicente Mut and dated 1683. Mut wrote several publications on artillery, astronomy and history, and worked on the fortification of Majorca. As an historian and chronicler, Mut is best known for his Historia del reyno de Mallorca (Palma, 1650) written in continuation of Juan Dameto's Historia general del reino de Mallorca. Mut searched the archives with great diligence, and gives valuable details respecting the administration of the island at different periods.

Mut was one of the first scientists to make use of a micrometer to determine the angular size and distance between objects observed with a telescope. He used this device since 1653, before Christiaan Huygens described it in his treatise Systema Saturnium (1659). According to Riccioli Mut was the first astronomer to measure the angular distances in the Pleiades.

Mut's Tratado de arquitectura militar (1664) contains the first known attempt to use Galilean mechanics in the study of the trajectory of projectiles and one of the first references to the new mechanics in the printed Spanish literature of the seventeenth century.
