Federico Cesi

Federico Angelo Cesi (; 26 February 1585 – 1 August 1630) was an Italian scientist, naturalist, and founder of the Accademia dei Lincei. On his father's death in 1630, he became briefly lord of Acquasparta. Biography Federico Cesi was born to an aristocratic family highly connected in Rome and the Papal States. The family derives its name from Cesi, a little town near Rome. They had a close connection with the Catholic Church, Frederico's uncle Bartolomeo Cesi was a cardinal in the church, and most of their wealth came from that connection. Federico was the first of eleven legitimate male children and was born in Palazzo Cesi, in via della Maschera d'Oro, Rome, on 26 February 1585. His father was Federico, marchese di Monticelli (1562–1630) and his mother was Olimpia Orsini of Todi. In 1614 Cesi was married to Artemisia Colonna, the daughter of Francesco, Principe di Palestrina; she died two years later. In 1617 he married Isabella, cousin of Filippo Salviati, the daughter of the Marquis of Lorenzo. In 1618 he moved to Acquasparta and lived there until his death at the age of forty-five. The Accademia dei Lincei ("Academy of the Lynxes") In 1603, at the age of eighteen, Cesi invited three slightly older friends, the Dutch physician Johannes van Heeck (in Italy Giovanni Ecchio), and two fellow Umbrians, mathematician Francesco Stelluti of Fabriano and polymath Anastasio de Filiis of Terni to join with him in the founding of the Accademia dei Lincei ("Academy of the Lynxes"), aimed at the understanding of all natural sciences through a method of research based upon observation, experiment, and the inductive method. Their goal was to penetrate the secrets of nature, observing it at both microscopic and macroscopic levels. The four men chose the name "Lincei" (lynx) from Giambattista della Porta's book "Magia Naturalis", which had an illustration of the fabled cat on the cover and the words "...with lynx-like eyes, examining those things which manifest themselves, so that having observed them, he may zealously use them". Cesi chose the sharp-eyed lynx and the eagle for the academy's symbols. The academy's motto, chosen by Cesi, was: "take care of small things if you want to obtain the greatest results" (minima cura si maxima vis).
