Leonardo da Vinci (1452 to 1519), was ahead of his time in his investigations of the concept of gravity. His research was first discovered in the Codex Arundel, a compilation of da Vinci's writings on topics that included science, art, and personal experiences. In his notes, da Vinci detailed an experiment in which a water jug was moved parallel to the ground, releasing either water or sand. He observed that the sand or water would accelerate and fall at an entirely downward acceleration due to gravity. Additionally, da Vinci observed that the horizontal acceleration of the material stopped, implying that there was no more external force being applied to it. Unfortunately he used an incorrect equation, still, his insights into the concept of gravity were significantly ahead of his time. The paper is here but unfortunately protected by a paywall. https://direct.mit.edu/leon/article-abstract/doi/10.1162/leon_a_02322/113863/Leonardo-da-Vinci-s-Visualization-of-Gravity-as-a?redirectedFrom=fulltext

BBCs "In Our Time: History", Daniele Bolelli's "History on Fire" he does an excellent job on narrative but a major complaint I've heard is his voice can be a bit hard to understand since he's a native Italian speaker, "Stuff you missed in History class", Malcolm Gladwell's "Revisionist History"
