A portrait of Marcello Malpighi from his book Opera posthuma: figuris aeneis illustrata, quibus praefixa est ejusdem vita a seipso scripta, Londini:Churchill, 1697. Inscription: Marcellus Malpighius | Medicus Bononiensis mortuus 29 Novemb. Anno Dom. 1694. Anno aetatis 67. I. Kip. sculp.

Marcello Malpighi (10 March 1628 – 29 November 1694) was an Italian biologist and physician, who is referred to as the "Father of microscopical anatomy, histology, physiology and embryology" [Wikipedia].

From European Journal of Anatomy 22(5):433-439 · September 2018, an article by Sanjib Ghosh and Ashutosh Kumar 'Marcello Malpighi (1628-1694): Pioneer of microscopic anatomy and exponent of the scientific revolution of the 17th Century': Italian anatomist and an eminent scientist who significantly contributed to the advancement of the anatomical sciences in the 17th century. Malpighi was one of the first to use the compound microscope (an instrument designed by Galileo in 1609) and made the most important discovery of his life in 1661 when he identified capillaries as connecting vessels between small arteries and veins in the lungs. Malpighi thus provided the missing link in William Harvey's theory of blood circulation. He made significant contributions in the field of embryology based on his observations on chick embryo, and his efforts provided deep insights into the development of the heart and the nervous system. His communications based on microscopic studies scripted valuable details on the structural organization of organs like the liver, kidney and spleen. He identified the hepatic lobule as the fundamental unit of the liver and noted that bile was being secreted by these lobules and not from the gall bladder (the popular belief then). In the kidney, he discovered the glomerulus (Malpighian Corpuscle) and was the first to observe the convoluted tubules in the renal cortex. He was the first to describe the presence of lymphatic bodies (Malpighi's Corpuscle) in the spleen. Although he was exceedingly successful in his scientific activities, his life was fraught with unfortunate events and savage criticism from detractors arising out of professional jealousy and personal feuds. Nevertheless, his exploits were instrumental in understanding the human microscopic anatomy (histology) and his accomplishments have etched his name in the pages of medical science forever.

The portrait was engraved by Johannes "Jan" Kip (1652/53, Amsterdam – 1722, Westminster) - a Dutch draftsman, engraver and print dealer.

Quotation from Phyllis D. Massar. Presenting Stefano della Bella. — NY: The Metropolitan Museum of Art, [1971]: "For size and complexity, one of Della Bella's most impressive achievements is his view of Paris across the Pont Neuf from a point between the buildings bounding the Place Dauphine. Besides the well-known landmarks-the Hộtel de Nevers, the Tour de Nesle, the church of Saint Germain l'Auxerrois, and, at the centre, the bronze equestrian statue of Henri IV by the Florentines Giovanni Bologna and Pietro Tacca – the print provides a microcosm of Paris in transit across the Seine. With a glass, one can compile a census of 451 people, thirty-eight horses, nineteen dogs, three donkeys, and one lamb. All but lost in the vast scene, nevertheless, all contributing to it, are duelists, men fighting with staffs, brawlers routing passers-by, a tooth-puller making an extraction, sellers of sweetmeats and fruits, falconers, hunters with a pack of dogs, a legless cripple, many begging gypsies (one of them telling a fortune), and a hurdy-gurdy player with an audience. Moving among the splendid carriages is a humble water cart, and back among the market stands at the right is an early Seine-side bookstall."
