Publius Herennius Dexippus (Greek: Δέξιππος; c. 210 – 273 AD), Greek historian, statesman and general, was an hereditary priest of the Eleusinian family of the Kerykes, and held the offices of archon basileus and eponymous in Athens.
When the Heruli overran Greece and captured Athens (267), Dexippus showed great personal courage and revived the spirit of patriotism among his fellow-countrymen. A statue was set up in his honour, the base of which, with an inscription recording his services, has been preserved. It is remarkable that the inscription is silent as to his military achievements.
Photius (cod. 82) mentions three historical works by Dexippus, of which considerable fragments remain:
- Τὰ μετ᾽ Ἀλέξανδρον (The Events after Alexander), apparently an epitome of a work by Arrian
- Σκυθικά (Scythica), a history of the wars of Rome with the Goths (called Scythians in archaizing language) in the 3rd century
- Χρονικὴ ἱστορία (Chronike Historia) in twelve books, probably covering a thousand years to the reign of the emperor Claudius Gothicus (270)
The Chronicle was continued by Eunapius of Sardis, who opens his own history with a critique of his predecessor. The Chronicle also appears to be the primary source of the Historia Augusta between 238 and 270, but Paschoud has demonstrated that the author of the Historia Augusta sometimes attributes material to Dexippus falsely, and so this evidence must be used with caution.
