In the myth called the Destruction of Mankind, related in the "Book of the Heavenly Cow" from the New Kingdom (c. 1550–1070 BC), Ra uses the Eye as a weapon against humans who have rebelled against his authority. He sends the Eye—Hathor, in her aggressive manifestation as the lioness goddess Sekhmet—to massacre them. She does so, but after the first day of her rampage, Ra decides to prevent her from killing all humanity. He orders that beer be dyed red and poured out over the land. The Eye goddess drinks the beer, mistaking it for blood, and in her inebriated state returns to Ra without noticing her intended victims. Through her drunkenness she has been returned to a harmless form. Nadine Guilhou suggests that the Eye's rampage alludes to the heat and widespread disease of the Egyptian summer, and in particular to the epagomenal days before the new year, which were regarded as unlucky. The red beer might then refer to the red silt that accompanied the subsequent Nile flood, which was believed to end the period of misfortune.
