Since Fingerprints of the Gods (published in 1995) I have maintained that embedded in certain ancient maps – notably the so-called Portolan Charts of the 13th to 15th centuries AD – are accurate representations of geographical features that no longer existed when the maps were made but that were present thousands of years earlier. The mystery deepens when we realise that these maps are in every case based on and copied from much older source maps that are now lost.

Now a 2015 radar survey of Mauritania, with imaging from a Japanese Earth observation satellite, has revealed the existence of a vast ancient river network beneath the shallow, dusty surface of the Western Sahara, winding its way from deep inland towards the coast. The network, which may also extend much further to the east than the area covered by the survey, dried up and vanished from view more than 5,000 years ago but was in existence and kept the Sahara fertile for many thousands of years before that. For full details see these reports:


It is surely significant (see attached illustration) that an identical river system is shown in the Western Sahara in ancient Portolan Charts such as the Canepa Map (1489) based on older, lost source maps. It continues to be my position that those source maps were the work of an advanced civilization that flourished more than 13,000 years ago but that was destroyed in the global cataclysmic episode known as the Younger Dryas between 12,800 and 11,600 years ago.

My new investigation of the lost civilization mystery, the sequel to Fingerprints of the Gods, is Magicians of the Gods (published on 10 September 2015 in the UK and on 10 November 2015 in the US). For more on Magicians of the Gods, see here:

    Ecellent research and thought. Many thanks for your dedication. Best Regards.

    Brilliant Graham, would love to know what you think about extending your work on linking ancient civilizations to constellations as you did with Draco/Angkor Wat. I’ve posted a few on the Mysteries board – Ollantaytambo/Centaurus, Stonehenge/Sagitta, Knossos/Corona Borelais, Easter Island/Ara (evidence at each site ranges from artifacts, geometry, the predominate myth and ritual). thanks Robert

    Received “Magicians” yesterday and just finished Part 1. Excellent, Mr. Hancock! As always, content, insight, and explanation is comprehensive and easy to absorb. Few proofing issues on the American version (p. 11, “Tepe” vs. “Tepi”; p. 13, inconsistency numeral vs. written-out number), but that’s just how it is! Best, Anthony.

  4. Come on Graham, who do you think named it Tamanrasett?

  5. Michel Demaria says:

    Excellent information, and consistent with “Underworld”. Thank you.
    One question about this ancient river: Have we indications on its spring, and the origine of its waters, also.
    Are there more informations about the related submarine canyon which would indicate the existence of a former submerged estuary. This would give more weight to theories on submerged canyons on both sides of the Atlantic, including the Agadir canyon in Morocco.
    It is consistent with ancient writings describing an inland sea at the eastern foot of Atlas Mountains.

    just a personal comment about last post (opinion)
    “Come on Gra
    ham, who do you think named it Tamanrasett?”
    My opinion: “Ta-Mana-Ra-Seth” name means “Place of the Spirit of Ra and Seth”. Similar to Taouz (Morocco) and Tozeur (Tunisia): “Ta-Ousir”, “Place os Osiris”.
    But it sounds Egyptian!;! Yes….

    Quite some time ago, in one of my articles for “Atlantis Rising,” I wrote about the Holocene Optimum which began not long after the last ice age ended. The Earth continued to warm, and from roughly 10,000 B.P. to about 5,000 B.P. was much warmer than at any time since. Due to increased evaporation of sea water, there was more precipitation worldwide. There may well be buried cities in the Sahara, near the ancient rivers, and the Bolivian altiplano would also have been warmer and wetter than today…perhaps many of the ancient structures there and in Peru were built during this period.

    Having read this I thought it was very informative.
    I appreciate you taking the time and energy to put this content together.
    I once again find myself spending a lot of time both reading and posting comments.

    But so what, it was still worth it!

    Hello Sir,
    Mr Handcock, I read finger Prints of the Gods 30 yrs ago when in high school and your work has had a life long impression on me. I was wondering if you are ever coming anywhere near my city for talks lectures. I am from Cornwall Ontario Canada,, a hour from Ottawa and Montreal.
    thank you again ,
    read your web page everyday that I can.

      Graham is in Toronto in support of his new book on Dec 13 2015. contact the conspiracy culture bookstore in toronto for tickets.

      regards, Brett.

    I would like to see Graham explore the connection
    between the Atacama humanoid tear drop shape skull
    that Greer did the video on and the same shaped
    helmet of some Egyptian pharaohs! We might learn
    some very interesting things.

    Hello Graham.
    I have checked in with your site daily for well over a year since discovering it, and look forward to reading both your books. Forgive me if you’re familiar with this, but in G.I. Gurdjieff’s book, “Meetings with Remarkable Men”, he relates being very excited to have come into possession of a map of “pre-sand Egypt”, which seems to have altered the course of his search for sources of ancient high knowledge of man, providing either greater insight or perhaps confirmation of things he knew or suspected about the real nature of ancient Egypt. I believe as he describes it, the map also indicated that the Sphinx was much older than conventional archeology supposes. No information was provided as to the source or fate of the map. Thank you for all you bring to the fore, Art weber

    i’ve just bought the book by Hapgood! i love your suggestions of books! i’m glad i have already some!
    just watching your documentaries now! amazing!

    somewhere you are saying that the bearded man with the snuff box is found everywhere, but the Egyptian one is carrying the cross of Anhk, so i was wondering if the cross of Anhk is a snuff box?

  12. Anthony Wynands says:

    Hi Mr. Hancock,
    I’m not certain if this would be the best place to do this, but I’m not certain where else would be appropriate. In “Magicians of the Gods,” in the American version, on page 219 of Chapter 10, there’s a reference to end-note “76”; however, there is no occurence of this end-note in the References on page 473.
