Gregory Aldrete

American historian. Professor of history and humanities at the University of Wisconsin-Green Bay. Specialises in ancient Rome — particularly military history, daily life, and material culture. Known for experimental archaeology: his linothorax project (reconstructing Greek and Macedonian linen armour from first principles, using ballistics testing) became a multi-year research programme with 150 students and a documentary. Also known for his work on Roman floods, Roman clothing, and Great Courses lectures on ancient history.

Author of Floods, Famines, and Emperors: El Niño and the Fate of Civilizations (with co-author); Gestures and Acclamations in Ancient Rome; and The Long Shadow of Antiquity (with Kelly Moss Aldrete). His method: hard science and practical reconstruction in the service of historical questions — not symbolic interpretation.


Background

Aldrete’s approach to history is practical. “Almost all my books started with simple ‘how did something work’ questions.” He brings a scientific background — hydraulics, vectors of disease, ballistics — to questions usually answered through texts alone. The linothorax project originated when an undergraduate student made a prototype; it became Aldrete’s tenure project and a significant contribution to experimental archaeology.

Known for: linothorax experimental archaeology; the integration thesis as Rome’s key to success; scale comparisons (Cannae vs Vietnam/Gettysburg) as pedagogical tools; Roman law vignettes as social history.

Key positions

  • Rome’s early success was manpower through integration, not military technology or generalship superiority
  • Hannibal’s double envelopment at Cannae is the most important tactical innovation in ancient military history — and Rome’s survival of it was its true transformation into a dominant power
  • Roman tactical flexibility (subdivided cohorts) defeated Macedonian phalanx frontal power at Cynoscephalae — flexibility beats mass
  • Linothorax was practical protective armour comparable to bronze at a fraction of the weight and cost, producible domestically
  • Structure outlasts charisma: Alexander’s empire vs Rome’s enduring institutions is the clearest ancient proof
  • Roman law — ~90% of world legal systems — is antiquity’s most durable contribution to civilisation
  • The mos maiorum (way of ancestors) simultaneously legitimised Roman conservatism and was weaponised to justify Caesar’s assassination
  • Roman slavery was not racial but was fundamentally dehumanising; the institution’s permeability does not mitigate its horror
  • “Othering others is morally corrosive thing to do”
