Six slides reviewed. Voice, density and member-value are all on-brand — the opener hooks, the mythology on slide 5 is the strongest beat, and MUNA on slide 6 gives the reader one concrete place to go. But three factual errors sit in the foundation highlight of the whole insight, and one of them (slide 6's Madrid return) is verifiably false. A wrong fact on a 2,000-year heritage story erodes trust in every other highlight it anchors — Pierre and Clara both catch it in the persona lens.
The three must-fix claims, from research: (1) “Guanche means son of Tenerife” — etymology is person of Tenerife (guan + achinet). Opening line of the whole highlight. (2) “Three more were returned from Madrid in 2011” — false. Spain has rejected repatriation requests; the Madrid mummy was only removed from exhibition in February 2025, not transferred. (3) “organised in extended family groups along matrilineal lines” — matrilineal succession applied to Gran Canaria, not Tenerife. Bencomo to Bentor is a patrilineal father-son line.
Slides 1, 3, 4 and 5 are close to ship-ready — cosmetic space-before-colon and small rhythm fixes aside. Slide 2 needs the matrilineal word-swap. Slide 6 needs a full rewrite of the repatriation paragraph and, ideally, a closing pointer that replaces the disputed tangent. Until all three factual errors are corrected, overall verdict stays ❌.
Optional recommendations
Add a dedicated gofio slide. This is the insight-level add-slide recommendation from Workflow A, and all three personas in the lens landed on it independently. Gofio is mentioned once in slide 3's body and again in the guide-note, but never explained at depth — it's the single most enduring Guanche legacy on today's Tenerife menus. A traveller sees it on six breakfast cards in the first week and has no story for it. Small addition, high payoff. Suggested placement: new slide 4, pushing “The Nine Kingdoms” to slide 5.
Consider replacing slide 6's repatriation tangent with the MUNA anchor expanded — what you see, how long it takes, where it is — plus a pointer to the Güímar pyramids or cave sites for the traveller who wants to physically touch the story. This solves two problems at once: removes the disputed Madrid claim, gives Lena & Théo a place they can photograph.
Pick up the insight-level typography fix (space-before-colon) across any future slide additions. This highlight doesn't currently contain the pattern, but the rest of the insight does.
Research
Disputed claims (must fix before ship)
“Three more were returned from Madrid in 2011” — false. The Guanche mummy at Madrid's National Archaeological Museum has NOT been repatriated. The Canary Islands government's requests have been rejected by the Congress of Deputies multiple times. As of February 2025, the Ministry of Culture only announced removal from exhibition — not transfer to Tenerife. No record of a 2011 return of multiple mummies from Madrid exists. Source: Wikipedia — Guanche mummy of Madrid.
“Guanche means son of Tenerife” — etymology is wrong. Derived from guanachinet, meaning “person of Tenerife” (Guan = person, Achinet = Tenerife). One-word fix but it is the opening line of the highlight. Source: Wikipedia — Guanches.
“organised in extended family groups along matrilineal lines” — wrong for Tenerife. Matrilineal hereditary autocracy applied specifically to Gran Canaria. Tenerife's kingdoms were patrilineal menceyatos — Bencomo to Bentor is a father-son line that confirms this. Source: Wikipedia — Guanches.
Verified claims (safe to keep)
The Guanches arrived from North Africa in several migratory waves, Berber in origin. Wikipedia — Guanches — high confidence.
The nine kingdoms were Daute, Icod, Taoro, Tacoronte, Tegueste, Anaga, Güímar, Abona and Adeje. Wikipedia — Guanches — high confidence.
Gofio — the Guanche staple still eaten daily on Tenerife. Appears only as a passing mention. Suggested placement: add slide to guanche-people. This is the Workflow A recommendation for this highlight and it is echoed by all three personas in the lens.
Persona reactions
Agreement: All three personas converge on two things. Slide 6 is the weakest beat — the false Madrid return is a trust-killer for Pierre and Clara, and Lena & Théo find it dry. Gofio needs a real slide — Pierre wants the legacy-to-today link, Clara wants to know what to do with the word on menus, Lena & Théo want to know where to eat it.
Conflict: Pierre and Clara want more historical depth and verification; Lena & Théo find slides 2 and 4 already too dense. Genuine conflict, not a split-the-difference fix — the primary audience for a Guanche highlight is Pierre-style, so keep the depth and add one “go see this today” anchor per slide so Lena & Théo have a visual handhold (the Güímar pyramids at sunset; Las Cañadas as a forbidden sacred place; a named cave).
Persona-driven fixes (priority order):
Fix the three factual errors before anything else. Pierre and Clara both notice and lose trust in the entire insight.
Add a dedicated gofio slide. All three personas want it, from different angles. Smallest addition, highest payoff.
Give slide 6 a confident “go see this” anchor — MUNA is good; add the Güímar pyramids or a cave site and close with a pointer, not a disputed tangent.

Current
Guanche means son of Tenerife. It is the name of the people who lived on this island for two thousand years before the Spanish arrived.
Every town name you pass on this island is a Guanche kingdom name. Tacoronte, Adeje, Güímar, Anaga. This is their story.

Why.“son of Tenerife” → “person of Tenerife”. Research-verified etymology. The rest of the overlay lands.
Why. The opening line carries a factual error — son of Tenerife is a popular mistranslation; the actual etymology is guan (person) + achinet (Tenerife) = person of Tenerife. One-word swap, but it's the first sentence in the foundation highlight of the whole insight.

The Guanches arrived from North Africa in several migratory waves, Berber in origin. They found a rugged island divided in two by a central massif, with deep valleys at La Orotava in the north and Güímar in the south. They called the island Achinech.They settled in mountain caves, organised in extended family groups along matrilineal lines, raised goats and grew wheat and barley.

Why. Removed “organised … along matrilineal lines” — wrong for Tenerife. Split Achinech.They → Achinech. They (missing space). Left the social-organisation detail simple rather than introducing “patrilineal menceyatos” here — slide 4 already explains the menceyatos and owns that beat.
Why. Matrilineal succession applied to Gran Canaria's Guanche society, not Tenerife's. Tenerife's kingdoms were patrilineal menceyatos — Bencomo to Bentor (told in The Conquest highlight) is a father-son line. Keeping “matrilineal” here contradicts The Conquest and the research source. Also split the Achinech sentence where the period is missing a space.

The Guanche language went extinct by the early 17th century. But some words remained in use. Gofio, toasted and ground grain, is a Guanche word still at the centre of Canarian cooking today.

Why. Close to ship. One rhythm tweak on the body — the laurisilva sentence floats between the cave-dwelling beat and the food beat. The gofio mention here is the seed for the recommended new slide; leave it for now but see Optional recommendations.

After the last unified king, Tinerfe the Great, died, his nine sons divided the island into nine kingdoms called “menceyatos”. Each was governed by a king. The nine kingdoms were Daute, Icod, Taoro, Tacoronte, Tegueste, Anaga, Güímar, Abona and Adeje. Most town names on the island today come directly from those kingdoms.

When the Spanish invaded, five northern kingdoms fought back. Four southern kingdoms chose peace and allied with the invaders. That split shaped the entire course of the conquest.

Why. Ship-ready. The nine-kingdoms roll-call plus the north/south split is the kind of structural detail Pierre flagged as the strongest part of the highlight. Only cosmetic: the word menceyatos uses curly quotes in the source — the renderer preserves them, but ensure the CMS entry keeps them consistent with the rest of the insight.

The Guanches believed the Teide was hell. They called it Echeyde. The name Teide comes directly from that word. Inside lived Guayota, demon of evil, locked there by the supreme god Achamán as punishment for abducting Magec, the god of light. The National Park was sacred and forbidden.They mummified their dead using cattle fat and animal skin wrappings, a process called mirlado, preserving skin and muscle for centuries.

Why. Added the missing paragraph break between “sacred and forbidden” and “They mummified their dead”. Two distinct beats — mythology and mummification — read better separated.
Why. Strongest slide in the highlight — the Echeyde / Guayota / Achamán / Magec mythology is the beat Théo would screenshot. One cosmetic split: the body copy is missing a space where the paragraph break lives.

Go see the Guanche mummies with your own eyes at MUNA in Santa Cruz — the largest collection anywhere, including the 2003 returns from Argentina.

Spain's Congress of Deputies has rejected repatriation requests multiple times; as of February 2025 the Ministry of Culture only removed it from exhibition. Leaving this in ships a wrong fact about a contested political process, on the highlight that anchors the whole insight. The proposal below keeps the Argentina 2003 beat (verified, confidence high) and replaces the Madrid sentence with what actually happened and a “go see” pointer that matches the MUNA guide-note's existing intent.
