Summary

Written by a model from the transcript; not yet reviewed.

This episode of The Ancients features host Tristan Hughes and guest Professor Edmund Richardson exploring the legendary siege of Tyre in 332 BCE and the brilliant, eccentric military engineer Diades. Often overshadowed by Alexander the Great, Diades reshaped ancient warfare by designing a massive, one-kilometer artificial promontory and colossal torsion catapults to conquer the seemingly impregnable island city. The conversation details the high-stakes chess match between Macedonian engineering and Tyrian chemistry, including devastating fireships and molten sand defenses, culminating in the brutal fall of Tyre and its lasting archaeological legacy.

  • Build artificial land bridges when geography protects an enemy stronghold. 32:06
  • Utilize torsion catapults to give missile weapons the power needed to threaten stone fortifications. 16:43
  • Deploy fireproof siege towers to protect workers and maintain offensive momentum during urban sieges. 47:23
  • Attack from multiple directions simultaneously once a breach has been created in defensive walls. 1:08:52

    Closing Reflections and Future Episodes

    The hosts wrap up the discussion, hint at a future episode on the Siege of Rhodes, and thank the guest.

Highlights

  • 8:42

    Diades as the Original Mad Scientistinsight

    Professor Edmund Richardson explains how Diades earned the label of a mad scientist because his ideas completely reshaped reality and pushed past conventional boundaries.

  • 33:27

    Tyrians Mock the Causewy Constructionstory

    When Alexander's army started dumping rocks into the sea to build a land bridge, the Tyrians sailed out on pleasure boats to mock the arrogant and foolish undertaking.

  • 42:42

    The First Advanced Fireship Attackstrategy

    The Tyrians loaded an old horse transport with pitch, bitumen, and straw, towed it in the dead of night, and crashed it into the Macedonian promontory as a massive fireball.

  • 53:44

    The Surviving Causeway of Tyreinsight

    Professor Edmund Richardson notes that the ancient kilometer-long promontory built by Diades is still visible today, permanently altering the geography of Tyre.

  • 1:00:16

    Tyrian Chemical Warfare with Molten Sanddata

    Defending the walls, the Tyrians heated sand to over 1,000 degrees Fahrenheit in stone vats and fired it via catapults to horribly torture attacking Macedonian soldiers.

About this episode

WARNING: graphic descriptions of violence and warfare Meet Diades, Alexander the Great’s overlooked military engineer, the man who made the impossible siege of Tyre happen. Tristan Hughes and Professor Edmund Richardson retell the thrilling, brutal, brilliant story of invention, ambition, and ancient warfare at its most extreme. In 332 BC, he turned a coastal blockade into a 1km causeway, then faced fire ships, molten sand, and a city that refused to yield.
