Some Landmarks in the History of the Hippocampus Morphology From Arantius’ 1587 Anatomicarum Observationum Liber

Abstract The hippocampus is undoubtedly one of the most fascinating components of the central nervous system. It was discovered and named in 1587 by Italian anatomist Giulio Cesare Aranzio (1530–1589), and it was depicted for the very first time in 1729 by German anatomist and botanist Johann Georg Duvernoy (1691–1759). The hippocampus, sometimes referred to as Ammon’s horn in relation to the Egyptian god, is a curved elevation in the floor and the medial wall of the temporal horn of the lateral ventricle of the brain. It is part of a set called the hippocampal formation, which primarily includes the dentate gyrus and the subicular complex, and occasionally the entorhinal cortex. This formation is part of a larger complex, named the limbic system, which was first introduced in 1878 by French anatomist and anthropologist Paul Broca (1824–1880).
