Most of the ancient witnesses group Manetho together with Berossos, and treat the pair as similar in intent, and it is not a coincidence that those who preserved the bulk of their writing are largely the same (Josephus, Africanus, Eusebius, and Syncellus). Certainly, both wrote about the same time, and both adopted the historiographical approach of the Greek writers Herodotus and Hesiod, who preceded them. While the subjects of their history are different, the form is similar, using chronological royal genealogies as the structure for the narratives. Both extend their histories far into the mythic past, to give the deities rule over the earliest ancestral histories.
