Brand: Plinius
"Hiato" is a Latin word meaning "opening" or "gap." In anatomy, it refers to an opening or space between two structures that should be closed or connected, but is not. For example, a hiatal hernia occurs when the opening (hiatus) in the diaphragm through which the esophagus passes becomes enlarged, allowing a portion of the stomach to push up into the chest. Plinius was a Roman author, naturalist, and naval commander who lived during the 1st century AD. While he is known for his encyclopedic work "Naturalis Historia," or "Natural History," which covered a wide range of topics from astronomy to zoology, he did not write extensively about anatomy or physiology. However, some Renaissance scholars, attempting to reconcile Galen's anatomical works with the later discoveries of Vesalius, mistakenly attributed to Plinius descriptions that were actually found in earlier medical works such as Galen's "On Anatomical Procedures." These mistaken attributions were known as the "Plinian accounts" and persisted for centuries. Thus, the term "hiatus" in anatomy is named after Plinius, who was credited with its discovery in medical literature that were actually written earlier.
