The Sothic cycle refers to a period of time in ancient Egyptian chronology that is based on the heliacal rising of the star Sirius (known as Sothis in Greek). This event occurs when Sirius first becomes visible in the eastern dawn sky just before sunrise, typically aligned with the annual flooding of the Nile River, which was crucial for agriculture in ancient Egypt.
