Eupolemus is the earliest Hellenistic Jewish historian whose work survives only in five fragments (or possibly six fragments) in Eusebius of Caesarea's Praeparatio Evangelica (hereafter abbreviated as Praep.), embedded in quotations from the historian Alexander Polyhistor, and in the Stromata (hereafter abbreviated as Strom.) of Clement of Alexandria. A sixth passage which Polyhistor attributes to Eupolemus in Eusebius' quotations of Polyhistor is usually considered spurious as being dissimilar to the other passages quoted and has come to be called Pseudo-Eupolemus.
