During the 25th and 26th Dynasties, the "Book of the Dead" was updated, revised and standardised. Spells were ordered and numbered consistently for the first time. This standardised version is known today as the 'Saite recension', after the Saite (26th) Dynasty. In the Late period and Ptolemaic period, the "Book of the Dead" continued to be based on the Saite recension, though increasingly abbreviated towards the end of the Ptolemaic period. New funerary texts appeared, including the "Book of Breathing" and "Book of Traversing Eternity". The last use of the "Book of the Dead" was in the 1st century BCE, though some artistic motifs drawn from it were still in use in Roman times.
