The arrival of spring
As mentioned, each society has its own way of explaining natural phenomena, and the ancient Egyptians had a very particular way of explaining the Nile floods and the sowing season. According to Egyptian mythology, spring is born because of the death of Osiris at the hands of his brother Seth. Osiris, agricultural god and king of the gods, was married to Isis, and his brother Seth was married to Nephthys, Isis’ twin sister. Osiris one night had sex with Nephthys, mistaking her for his wife, and Seth upon finding out, decided to kill Osiris, and thus also get the throne of his brother. Osiris died, and his dismembered body ended up in the Nile. Isis mourned the death of her husband, and sank the Nile with her tears, which caused it to overflow and bathe the nearby areas and the harvest began to come out. An interesting way to explain the sowing season and spring. But she did not give up, and with her power and that of Nephthys, they mummified and recomposed Osiris to bring him back to life. To non-life, because he was still in the world of the dead.
