Episode Details

Host Matt Trump wraps his London walking tour series and turns to a topic he calls preposterous, seductive, and genuinely fun: the Phantom Time Hypothesis, the claim that roughly 300 fabricated years were inserted into the Western calendar. He traces the idea back to his 1990s medieval-history hobby, credits the theory to Heribert Illig, and lays out its wild premise, that Holy Roman Emperor Otto III and Pope Sylvester II may have engineered the years AD 614 to 911, possibly conjuring Charlemagne himself out of thin air.

True to form, he leans against the belief rather than into it, walking through how one might disprove it. The centerpiece is a live, screen-shared attempt to pin Pliny the Elder's recorded solar eclipse to NASA's eclipse tables, with results that get murky fast. Expect archives, lost libraries, calendar skepticism, and a promise to revisit the topic (and maybe the Khazars) later.
