The Frankish Kingdom after Clovis' death (511)

Year 511 (DXI) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Felix and Secundinus (or, less frequently, year 1264 Ab urbe condita). The denomination 511 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

  • Aryabhata, Indian astronomer and mathematician, comes up with concepts of mathematical equations, one of which explains the rotation of the Earth on its axis. This concept is far ahead of its time and he is fairly accurate in his description of it. He also comes up with a lot of other ideas about the Solar System, but many of them are flawed because he considers the Earth to be the center of the universe. Aryabhata is often given credit for coming up with the number zero and using it as a placeholder.
