What does the festival of inventio Osiris celebrate?

The festival of inventio Osiris is primarily focused on celebrating the resurrection of Osiris, who is one of the most significant deities in ancient Egyptian mythology. Osiris represents themes of rebirth and regeneration, often associated with agricultural cycles and the afterlife. The festival commemorates the myth in which Osiris is resurrected by his wife, Isis, after being murdered by his brother Set. This event symbolizes not only the fertility of the land but also the cyclical nature of life and death.

Understanding this context highlights the significance of resurrection in ancient Egyptian belief, where it was viewed as a crucial part of the life-death-rebirth cycle. Other options are not the focus of the festival: while the planting season and agricultural aspects do relate to Osiris's symbolism, they do not capture the specific essence of the inventio festival, which centers on his resurrection. Similarly, while the birth of Harpocrates and the ascension of Isis are important in their own right, they do not pertain directly to the central celebration of the resurrected Osiris during this festival.
