Gabriele Zerbi
Gabriele Zerbi (1445–1505) was a Veronese professor at the Universities of Bologna and Padua. He was also referred to as Zerbus, Zerbo, Zerbis, Gerbo, Gerbi, and Gerbus. He survived the devastating bubonic plague outbreak of 1477–79 in Northern Italy. He published the first printed treatise on geriatrics, "Gerontocomia: On the Care of the Aged," which took the form of a practical guide. His other works included: "Questiones Metaphysicae; De Cautelis Medicorum; Liber" "anatomiae corporis humani et singulorum membrorum" "illius;" "De anatomia infantiis et porci ex traditione" "Cophonis," and "Libellus de preservatione corporum a" "passione calculosa." Early life. Gabriele  Zerbi was born in Verona to Francesco and Paola. Not much is known about his mother, Paola, but in various community documents that mention his father, Francesco, it appears that he was involved in various duties of civic responsibility, including the financial affairs of Verona. He had two brothers named Benedetto and Giovanni as well as two sisters named Taddea and Angela, the former also being the name given to Zerbi's daughter. Academic career. While it is unclear exactly where Zerbi obtained his university degree, he spent notable amount of his youth in Venice, leading to the belief that  he studied at the University of Padua. It is also here that he began a four-year teaching post in philosophy starting in 1467 at the age of twenty-two. Zerbi also taught medicine and logic at the University of Bologna from 1475 to 1483. Between 1483 and 1494, Zerbi lived in Rome, but not much is known about his academic career during this time period. After living in Rome, he returned to the University of Padua to be a lecturer "de sero" between 1494 and 1505. In the summer of 1499 Zerbi went to Venice and practiced as a  physician; he avoided paying taxes other physicians had to pay by only practicing there during the school break. In May 1503 Lorenzino de Medici became ill and sent for a physician from Florence to come and treat him; Zerbi was chosen over Hieronimo da Verona and given leave of absence from his teaching position. Death. Zerbi's death came about after treating his last patient. He was summoned by Skander, chief minister of the sultan of the Ottoman Turks. Zerbi had fled from the wrath of Pope Sixtus, and Skander was ill with a severe case of dysentery. The doctor  brought along his young son on his visit to the Turks. After curing the prince, Zerbi received a large sum of gold, jewels, and other valuable items as payment. On his way home, however, the prince fell ill again and died due to not following Zerbi's instructions. His sons, thinking Zerbi had poisoned their father, pursued and captured Zerbi to punish him. They sawed Zerbi's son in half before him, then immediately sawed Zerbi in half as well. According to his will last dated on October 13, 1504, his wife Helena de' Metaselimi of Bologna and the godfather  of his children Pietro of Mantua were the executors of his estate. After her, his estate would go to his four sons: Paolo, Hieronymo or Girolamo, Marco, and Giovanni Aloisio. In addition, he gave money to his daughters, Taddea and Hermodoria, his sisters, Clara and Angela, his brothers, Giovanni and Benedetto, and to his nephew, Francesco. Works. His first work, "Questiones Metaphysicae", was a commentary on Aristotle's own "Metaphysics". "Gerontocomia" discussed the coping and treating of elderly. It discussed topics such as diet, optimal living situations, beneficial medicines, and how to ensure the physical well-being of the elderly . "De Cautelis Medicorum" was a text discussing the medical ethics that a practicing physician should follow. The text included what a physician's appearance should resemble, hygienic habits, and preferred spiritual beliefs. "Liber Anathomie Corporis Humani" "De Generatione Embrionis" was Zerbi's last published essay; it covered most of Zerbi's work on pregnant animals. Zerbi was a strong advocate for the code of physicians. This code includes six categories of rules all physicians should abide by. Zerbi gained much of his knowledge of human anatomy by dissecting various animals since human cadavers were scarce. By doing this, he opened  up the first discipline of comparative anatomy. He also was one of the first physicians to separate the organs into systems and focused his attention on the kidneys. He discovered veins do not enter inside the kidneys, but only reach their periphery. Zerbi hypothesized the kidneys act as a filter to filter liquid before it enters the bladder but other physicians doubted this.
