The paper devoted to Spell 148 of the Coffin Texts includes a review of the previous studies and a new Russian translation, accompanied by transliteration and supplied with comments. The myth touches on the birth of Horus by the goddess Isis. It has been preserved on five coffins dated to the 11th – 12th Dynasties, mainly come from Asyut (Upper Egypt). Being different versions of the same spell, these records allow to recreate a relatively complete exposition of the birth of the lord of gods and a future ruler, expressing the Egyptians beliefs common during the First Intermediate period.
