Final answer:
Akhet was the ancient Egyptian season of Nile flooding, vital for agriculture and significant to their culture, religion, and sense of order.
Step-by-step explanation:
Akhet was the season of flooding in ancient Egypt. The Egyptians divided their year into three seasons based on the cycle of the Nile River: akhet, peret (growing/emergence), and shemw (harvest). Akhet was a crucial time when the Nile flooded its banks, bringing water and fertile sediment to the land, which made it possible for agriculture to flourish. This annual flooding was predictable and so essential to life in Egypt that it became central to their religion, mythologies, and way of life, leading to a deep sense of cosmic order and justice, or Ma'at.
