# Pierre Belon

Pierre Belon (1517–1564) was a French traveller, naturalist, writer and diplomat. Like many others of the Renaissance period, he studied and wrote on a range of topics including ichthyology, ornithology, botany, comparative anatomy, architecture and Egyptology. He is sometimes known as Pierre Belon du Mans, or, in the Latin in which his works appeared, as Petrus Bellonius Cenomanus. The Russian physiologist Ivan Pavlov (known for Pavlov's dogs) called him the "prophet of comparative anatomy".

## Life

Belon was born in 1517 at the hamlet of Souletière near Cérans-Foulletourte in the Pays de la Loire. Nothing is known about his descent. Somewhere between 1532 and 1535 he started working as an apprentice to René des Prez, born in Foulletourte but by then an apothecary to the bishop of Clermont, Guillaume Duprat. Between 1535 and 1538 he entered the service of René du Bellay, bishop of Le Mans, who allowed him to study medicine at the University of Wittenberg with the botanist Valerius Cordus (1515-1544). He travelled around Germany with Cordus in 1542, and on his return, he travelled through Flanders and to England. By the end of summer in 1542 he continued his studies at Paris. With the recommendation of Duprat, he became an apothecary to Cardinal François de Tournon. Under this patronage, he was able to undertake extensive scientific voyages. Starting in December 1546, he travelled through Greece, Crete, Asia Minor, Egypt, Arabia and Palestine, and returned to France in 1549. A full account of his Observations on this journey, with illustrations, was published in Paris, 1553. Returning to the household of Cardinal de Tournon at Rome for the Papal conclave, 1549-1550, Belon encountered the naturalists Guillaume Rondelet and Hippolyte Salviani. He returned to Paris with his copious notes and began to publish. In 1557 he travelled again, this time in northern Italy, Savoy, the Dauphiné and Auvergne.
Belon was highly favoured both by Henry II and by Charles IX, the latter of whom accorded him lodging in the Château de Madrid in the Bois de Boulogne. There he undertook the translations of Dioscurides and Theophrastus. Belon was murdered, possibly by thieves, one evening in April 1564, when coming through the Bois on his return from Paris.

## Works

Belon was typical of the Renaissance scholar and took an interest in "all kinds of good disciplines" in his lifetime. He was interested in zoology, botany and classical Antiquity. Besides the narrative of his travels he wrote several scientific works of considerable value.
His first book was Histoire naturelle des estranges poissons (1551) and despite its title was a work mainly on the dolphin; it did have woodcuts of some fishes, possibly the first among printed books in the West.
His second book, De aquatilibus (in Latin, 1553) greatly expanded on the first and included a description of 110 species of fish, with illustrations; it was a work that laid the foundation of modern ichthyology. Its French translation La nature et diversite des poissons (Paris, 1555) was followed by an edition of 1560, and the volume was reprinted in Frankfurt and Zurich. His works were translated by Carolus Clusius, and he was held in high authority by the Italian naturalist Ulisse Aldrovandi.
In his L'Histoire de la nature des oyseaux (1555) he included two figures of the skeletons of humans and birds, marking the homologous bones. This is widely seen as one of the earliest demonstrations of comparative anatomy.
