Hecataeus of Abdera

Hecataeus of Abdera (Greek: Ἑκαταῖος ὁ Ἀβδηρίτης; c. 360 BC c. 290 BC) was an ancient Greek historian and ethnographer. None of his works survive; his writings are attested by later authors in various literary fragments, in particular his Aegyptica, a work on the society and culture of the Egyptians, and On the Hyperboreans. He is one of the authors (FGrHist 264) whose fragments were collected in Felix Jacoby's Fragmente der griechischen Historiker.

Historian John Dillery called Hecataeus "a figure of extraordinary importance for the study of Greek and non-Greek [cultures] in the Hellenistic period."
