How it changed

The deified star Sirius, whose reappearance in the dawn sky after weeks of invisibility fell close to the start of the flood, which made her its herald and the marker of the Egyptian new year. The slippage between that observed rising and the 365-day civil calendar is the Sothic cycle modern scholars use to anchor Egyptian dates. She merged with Isis in later periods, as Isis-Sothis.
