Quick summary
Steven Bartlett sits with Graham Hancock for a nearly two-hour conversation framed by Hancock’s upcoming open-heart surgery and a possible last long-form interview. Hancock argues humanity is a “species with amnesia” (crediting Immanuel Velikovsky’s Mankind in Amnesia): global flood myths encode a real end-Ice-Age cataclysm he ties to the Younger Dryas impact hypothesis (~12,800 years ago), comet fragments (Encke / Taurid stream), megafauna die-off, meltwater pulse, and a sudden warm-up ~11,600 years ago. He reads Portolan / Orontius Finaeus maps as evidence someone mapped ice-free Antarctica centuries before the official 1820 discovery; points to Göbekli Tepe hunter-gatherers, tropical Ice Age “real estate,” and Peru’s Caral-Supe as pieces of a forgotten episode. The episode’s deepest technical beat is Hancock’s Great Pyramid number cluster: a claimed Earth-scale of 1 : 43,200, mythic multiples of 72, Giorgio de Santillana’s Hamlet’s Mill and precession (~25,920-year great year), Rigveda syllable count, and older-than-Hipparchus knowledge — then Followers of Horus / Apkallu as transmission orgs. Later: Amazon geoglyphs, terra preta, lidar (Acre; Netflix Ancient Apocalypse), ayahuasca / DMT / Imperial College, Egyptian judgment / 42 assessors / Ma’at, childhood in Vellore India, Santha and family, and his response to racism accusations.

Timestamped outline
- 0:00 Cold open — possible last interview; hostile journalist; lost civilization / myths sewing scientific cataclysm data; “wake up” or become the next lost civilization.

Focus: 43,200, the number 72 & precession (~42:18)
All of the following are Hancock’s claims and interpretations as stated on tape — framed here as his argument, not as settled archaeology or astronomy pedagogy.
- 39:48–41:26 Setup: Great Pyramid aligned to true (astronomical) north within about 3 arcminutes (~3/60 of a degree) on a ~6-million-ton, ~481 ft (original height) monument; sits almost exactly on latitude 30°N — Hancock’s “one-third of the way between the North Pole and the equator.”
- 41:39–41:53 Hancock argues the pyramid encodes Earth dimensions at scale 1 : 43,200: height × 43,200 ≈ Earth’s polar radius; base perimeter × 43,200 ≈ Earth’s equatorial circumference.
- 41:55–42:08 He says archaeologists know the match and call it coincidence; Hancock replies he might agree if the scale weren’t specifically 1 : 43,200 — “the scale choice matters.”
- 42:18–42:23 Key line: those mythic numbers found worldwide are all multiples of 72.
- 42:23–42:42 Hancock cites Hamlet’s Mill by Giorgio de Santillana (MIT History of Science) as the authority who tied the numbers and imagery to the precession of the equinoxes.
- 42:44–44:29 Precession explained (Hancock’s demo): Earth’s axis wobbles; spring-equinox sun has been against Pisces ~2,000 years (Age of Pisces; early Christian fish symbol); next is dawning Age of Aquarius; pole star today Polaris, formerly Thuban (Draco); “great year” in the mythic convention he cites ≈ 25,920 years (≈2,160 years per zodiacal age × 12). He treats 43,200 as belonging to that 72-based precessional number family (43,200 = 72 × 600).
- 44:42–44:48 Hancock’s figure: 43,200 = number of syllables in the Rigveda — his example of the same number cluster “all over the world.”
- 45:05–45:14 Mainstream credit: Hipparchus of Alexandria discovered precession ~2,000 years ago; Hancock argues encoding precession in the pyramid implies older inherited knowledge from a “forgotten episode.”
- 47:19–49:16 Bartlett clarification loop; Hancock restates height → polar radius, sides → equatorial circumference; “this monument speaks to the Earth”; latitude 30 / true north as intentional Earth-lock.
- 49:58+ Transmission organizations (Hancock’s next-book tease): Egyptian Followers of Horus; Sumerian Apkallu / seven sages — pre-flood teachers, some surviving as post-flood advisers to kings; long-lived groups stewarding knowledge after cataclysm.
Related numbers (not claimed in this interview)
These notes are not from Hancock on this tape. They are a short spawn-off for later research pages.
- 43,200 seconds = 12 hours — half of a 24-hour mean solar day (43,200 ÷ 3,600 = 12).
- A4 = 432 Hz — a contested alternative to the common A440 concert pitch; modern advocacy often overclaims ancient or healing status. Source: Wikipedia · Concert pitch (see “Controversial claims for 432 Hz”).
- ~432,000-mile solar radius — the Sun’s mean radius is about 695,700 km (~432,000 miles when rounded). Sacred-number writeups often treat that rounded figure as meaningful; that folklore is separate from this interview. Source: Wikipedia · Sun (radius).

Stories
Possible last interview / hostile journalist
0:00 / 11:36 Hancock opens under the shadow of major heart surgery — failed valve, low energy, stairs hard — and a “tiny chance” this is the last time he speaks at length about his work. He refuses to name a journalist with “very bad blood” who, he says, is trying to publish a damaging portrait; he answers the caricature directly: not a grifter, not a hoaxer, not a con man.
The 72 / pyramid scale beat
41:39 After walking true-north precision and latitude 30, Hancock drops the scale claim: height × 43,200 → polar radius; perimeter × 43,200 → equatorial circumference. When the coincidence objection comes, he doesn’t fight the arithmetic — he fights the number. 43,200, he says, sits in a worldwide mythic sequence of multiples of 72, the same family Santillana traced to axial precession (Pisces → Aquarius, Polaris vs Thuban, ~25,920-year great year). Rigveda syllable count and Hipparchus are the punchlines: if the pyramid encodes precession, Hancock argues, the knowledge is older than the Greek discovery story.
Tropics as Ice Age real estate
23:43 Bartlett asks where you’d look for a missing Ice Age civilization. Hancock’s answer is almost real-estate blunt: not Siberia — the tropics, down toward the equator; Indonesia and similar bands are the logical “nice” land while ice locked the north.
Amazon lidar unlocks the canopy
1:05:37 Hancock describes geoglyphs once hidden under rainforest, terra preta still farmed in Brazil, and dense lidar over Acre with Martti Pärssinen (also on his Netflix series). The moral of the scene: the Amazon was not an untouched wilderness — it supported large populations whose earthworks lidar can finally map under canopy.
Ma’at’s feather and 42 assessors
1:30:40 Late episode, Hancock stages the Egyptian judgment hall: Osiris enthroned, Ma’at with the feather, heart vs feather on the scale, and 42 negative assessors asking whether you stole, killed, and more. The practical ask is modern — live so your heart doesn’t tip the balance; leave with as few regrets as possible.
Passing
Passing, unlinked: unnamed hostile journalist; comet research group colleagues; Old Kingdom laborers (as discussed); Apkallu / Followers of Horus as mythic collectives; early Christians / fish symbol; Dynasty 5–6 / Pyramid of Unas (brief); boarding-school peers; Bartlett’s product team; “deranged teenagers” / low-consciousness leaders as types; Taurid meteor stream (passing science name-drop beyond Encke).
