Pierre Belon (1517–1564) was a French traveler, 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. Ivan Pavlov called him the "prophet of comparative anatomy".
