No complete works of Hecataeus have survived, and knowledge of his writing exists only in passages (called "
fragments") from works by other ancient writers, most of which concern
religion. Eight fragments survive from his book about the
Hyperboreans, the mythical people of the far north. Six fragments survive from his
Aegyptiaca and regard Egyptian philosophy, priests,
gods,
sanctuaries,
Moses, and wine; they also mention the 4th century BCE Greek philosopher
Clearchus of Soli and the school of
gymnosophists. Hecataeus wrote the work
Aegyptiaca ( 320 – 305 BCE) or
On the Egyptians. Both suggestions are based on known titles of other
ethnographic works which contain an account of Egypt's customs, religious beliefs and geography. The single largest fragment from this lost work is held to be Diodorus' account of the
Ramesseum, the tomb of
Ramesses II, who is often referred to by the Greek rendition of his name, Ozymandias (i.47-50). According to Montanari, in Hecataeus's writing, Egypt is "strongly idealised" and depicted as a country "exemplary in its customs and political institutions". Hecataeus' excursus on the Jews in
Aegyptiaca was the first mention of them in
ancient Greek literature. It was subsequently paraphrased in Diodorus Siculus 40.3.8. Diodorus Siculus' ethnography of Egypt (
Bibliotheca historica, Book I) represents by far the largest number of fragments. Diodorus mostly paraphrases Hecataeus, thus it is difficult to extract Hecataeus's actual writings (as in
Karl Wilhelm Ludwig Müller's
Fragmenta Historicorum Graecorum). Diodorus (ii.47.1-2) and
Apollonius of Rhodes tell of another work by Hecataeus,
On the Hyperboreans. The early Christian theologian
Clement of Alexandria (c. 150 – c. 215 CE) (
Stromata 5.113) cites a work by Hecataeus entitled "On
Abraham and the Egyptians". According to Clement, Hecataeus was his source of verses from
Sophocles that praise monotheism and condemn idolatry. The main fragment explicitly attributed to Hecataeus in Jewish and Christian literature is found in
Josephus (
Apion 1.175–205), who argues in this fragment that learned Greeks (including
Aristotle) admired the Jews. and, according to ''
Brill's New Pauly'', its author was probably a
Hellenised Jew. According to the 10th century
Byzantine encyclopedia the
Suda, Hecataeus wrote a treatise on
Homer and
Hesiod, entitled
On the Poetry of Homer and Hesiod (). Nothing of this work survives, however, and it is mentioned by no other ancient source. ==References==
