As on previous occasions, the route of our camel trek through the Immidir will rest a day at Aguelmam Rahla, a reliable waterhole at the mouth of the Oued Tafrakrek canyon (blue line on map, left) where the Tissedit plateau drops down to meet a band of dunes. I’d been wanting to make a diversion here since scanning Google Earth a few years back and noticing the innumerable pre-Islamic tombs (‘PIZ’) in the area (below).

Looking again on Google Earth some time later, less than an hour of nosing around revelled three dozen keyhole, antenna or mound-ring tombs within a few kilometres of the waterhole. I didn’t bother counting the less distinctive mound tombs or just plain tumuli. In fact the proliferation of tombs here isn’t so unusual, given the topographic features already listed: edge of a plateau, former river mouth, band of dunes – all common factors found at former Neolithic occupation sites.

On the first crater tour in 2007 we walked along the base of the dunes, northeast from Aguelmam Rahla, and discovered several grinding stones and other artefacts at the foot of the dunes. And in 2012 one of us came across a near intact pot (left) at the foot of a dune, as well as napping (stone tool chipping) sites. You commonly find ceramic shards or even larger pieces, but I’ve never found an intact pot.

There’s something compulsive about Sahara tomb spotting on Google Maps, searching the featureless desert floor for the clear signs of prehistoric human activity. Once out there it can give a purpose to a journey that’s otherwise just agreeable recreation and adds a hint of treasure hunting.
It reminds you that the Sahara of 6000 years ago was not a desert, but a much less arid savannah. Among others, KenGrok spent years scanning and collating unusual imagery on Google Earth’s layers, including pre-Islamic tombs in the Sahara. In 2019 Google erased his work, but his baton has been picked up by ‘syzygy‘ on Google Earth Community, as well as Manfred Boelke at archaeoland.eu (his image below).

Broadly speaking, half a dozen tombs styles have been identified with clear regional limits as shown above. The most common is simply a mound of stones or tumulus which can be huge and can have a central depression to resemble a volcanic crater. Sometimes the mound may be surrounded by a ring – a mound-ring tomb. All over the Sahara tombs are usually found in clusters; find one and you’ll find others nearby. It suggests an auspicious place for burials or just a former occupation site with an adjacent burial ground.

A very unusual assembly of three types of tomb on the edge of the Tassili plateau near Djanet. The superimposed mound suggest the keyhole is older. As we know from rock art found in the same area, it’s common to cover what came before.

Antenna or crescent tombs have open arms spanning out from a tomb mound apex at around 120° and can be up to 250 metres or more, end to end. They are prolific in southeastern Morocco (bottom left; 27.6971, -10.8665), but are also found in Algeria by the thousand (25.86007, 4.36847). The finest ones have long, slender arms while small ones can be stumpy and even almost simple hemispheres.

Keyhole tombs are two concentric round or oval rings with the tomb mound near the middle and a corridor leading to the outer ring. Below is a famous keyhole near Djanet at the base of the Tassili n Ajjer plateau where you’ll find them in their hundreds.

A version of the keyhole is called a goulet tomb (below; French for narrow passage, as in ‘gullet’). They have a large perimeter ring with the tomb mound on the ring’s edge and a line or corridot of stones bisecting the circle. I find these much less common.

A version I’ve read about but not seen is called the rather ill-named compass tomb which is found exclusively in the Tibesti massif of northern Chad (left).
In the clearest examples like below, an arm or spike extends from the oval ring to one side, resembling a tadpole, tennis racket or snow show. As always, in the centre of the ring you will see the tomb mound.

Sunrise orientation
By now you may have spotted a common directional theme among the non purely circular pre-Islamic tombs: they all have elements which point at about 110° which, at these latitudes of around 25°N is towards the rising sun. Just as with many ancient, pre-monotheistic civilisations, the sun was the key element in their cosmology, with ‘the way to rising sun’ suggesting rebirth or afterlife. But just like builders, occasionally they got it wrong, like the compass tomb above right in the sands of the western Tibesti.

There is one final category of tomb which is also commonly foiund in the Sahara. The Islamic tomb. Contemporary Moslem cemeteries on the edge of desert towns are relative plain affairs, cleared rough ground covered in plain head stones. The ornate tombs below are out in the desert, far from the nearest village (Arak, Algeria). Usually the headstone is at the eastern end of the tomb, though of course with Islam that’s related to the direction of Mecca, not sunrise. These tombs, which might be said to have an entrance on the left and an east-pointing mihrab (‘altar’ niche) in the perimeter ring, will be a few hundred years old.

Islamic tomb

Not all pre-Islamic tombs fit the above categories. Below left, a keyhole shape but with no corridor, overlapped by a mound-ring tomb. Perhaps the corridor stones were reused for the mound-ring. Below right, a mound-ring with a perimeter mound like a goulet – a descendant’s tomb? I read here that excavated tombs in the Oued Draa of southern Morocco were more like mausolea, with a walled crypt under the stone mound where successive generations were interred. I’ve never read of a tomb being excavated like this in the Sahara, though I’m sure it must have been done, by either grave robbers, archeologists or the curious. I remember one time in the exceedingly remote Gilf Kebir, we came across a plain, desolate tomb (rare in that area) on a day-walk. Someone half-heartedly dug it up but found neither bones nor treasure. It didn’t seem like the right thing to do.

Often this fascination and excitement with pre-Islamic tombs falls a little flat on actually finding one on the desert floor. On a 2012 Immidir trip I was excited about finding a huge antenna tomb that lay close our path on Day 6 or so. On Google (above) the massive structure with a span of over 300m looked amazing, but by the time we tracked it down (left), it was too big to appreciate from ground level. My group seemed to say… ‘and the purpose if this diversion was…?’. ‘Flying’ over these tombs on satellite imagery, like Peru’s Nazca lines, is how they’re best appreciated.

How old are these ‘pre-Islamic’ tombs? Well in the central Sahara I’d say the Islamic era began to have an impact a couple of hundred years after the Arab Conquest of North Africa between AD 647–709. I imagine this swept like a tide west along the south Mediterranean coast, down the Atlantic to present-day Mauritania and then ‘eddied’ back west towards places like Timbuktu. Other eddies may have spun off sooner to places like Ghadames in Libya, following trans-Saharan trade routes into the interior.

Chances are these tombs, like the huge keyhole on the right in the Immidir (above), are only around 4000 years old, maybe double that. That means they followed the apogee of rock art some 6000 years ago following a climate change (the ‘Humide’ in the image below) which briefly repopulated populated what is now the Sahara. By this time megalithic tombs and temples became widespread across the ancient world, most spectacularly in ancient Egypt and western Europe.

You don’t have to venture into the deep Sahara to see keyhole tombs. In southern Morocco, just a short distance from Erg Chebbi and three miles west of Taouz, on the west side of the Oued Ziz are a cluster of tombs. Like Aguelmam Rahla they’re situated on the edge of a plateau and by a former big river as well as an erg – and not all with entrance ways pointing east.

Below, a curious structure on the Oued Tagant valley midway between Tam and Djanet. And below that, another in the Hoggar, just southeast of Assekrem. I’ve seen these elsewhere in southern Algeria but their meaning is unknown. The guides and old Saharan expeditions just call them ‘tombs’ but they look different and newer than PIZs.

Book review: Secrets of South Sahara ~ Mark Milburn (1979)

B is for Burials

In a line: must have been a great adventure so should have been a better story…

An interest in pre-Islamic tombs of the Sahara lead me to Secrets of South Sahara (£15 on ebay), Mark Milburn’s account of a solo expedition ostensibly to the western Aïr mountains near Arlit in 1976-7 to study these monuments. I figured it would make a more digestible introduction to the subject than the many dry or technical academic studies easily found on the web which anyway tend to be localised and/or specialised.

I was familiar with the name and am sure I once read another book of his, but Secrets… seems to be the only one available. Mark Milburn was also mentioned in the Sahara Handbook (1980) as an explorer and scholar of Saharan pre-history, through in this book he never describes himself as a professional  archeologist or academic, and comes across as merely a curious and well-read enthusiast. That may be incorrect or have changed since, as even today Milburn contributes many papers to publications in Spanish, German and French on the subject, including the now defunct Sahara Journal as recently as 2011. In fact you get the feeling he may have helped found SJ and even helped fund research in the Sahara. It’s hard to be sure about any of this as there’s little about [Dr] Mark Milburn on the web. He is perhaps a man of means.

As an account of desert travel just prior to the Golden Era when things got easier for a decade or so, the book itself was rather unsatisfying and inconsistent in pace. To be fair to the author, you get the feeling it was poorly edited by the American publishers who may have had little understanding of the subject or knowledge of the area. And there is no map! – always short-sighted with a book like this, so I’ve made a rough estimation on the left, based on his account. As you can see, he covered a fair amount of ground in Algeria and Niger.

The book starts with an overdetailed account of his descent from Germany to Spain to collect his desert gear stashed there. At times it reads like a diary and you’re left thinking, who cares what you had for breakfast or what letters you’ve received and from whom, let’s get on to the south Sahara. Already, an intense dissatisfaction with his vehicle is evident, as well as the people who service it, parts availability and so on – and it recurs right up to the very last paragraphs. It’s so bad he cannot even bear to utter the identity of his despised diesel, but from the photos it’s clearly a leaky-roofed 88” Land Rover.
This scorn is perhaps more understandable when he admits that a previous expedition was curtailed when a gear lever snapped off at the base (a not-unknown flaw on Series IIIs). His was towed back (afaict), but you get the feeling that temperamentally Milburn and Land Rover should never have walked down the aisle. Anyway the mid-1970s were the ‘Leyland years’ – the subterranean nadir of British automobile manufacture when shoddily assembled ‘Monday-morning vehicles’ were made three days a week. The other two days they were on strike.

This preamble drags on into protracted to-ing and fro-ing across the Morocco-Algerian border before he finally gets allowed in, followed by much grumbling about Algerian inefficiencies and inconsistencies. The county was then in the midst of its paranoid, Soviet-backed episode which I too recall from my early travels there, a time when even photographing telegraph poles (a hobby of mine at the time) risked arrest. The Western Sahara war between Morocco and Algeria was just kicking off in late 1976 too, and there was some doubt that the Algerian border would be open at all, or that there was access to the Grand Sud.

On his travels he meets other tourists exploring the Sahara, and near In Salah teams up with a driver with similar interests. They set off east along the piste towards Amguid village to check out old tombs. The gnarly stage beyond Tin Habedra well was one of a few episodes where the author managed to evoke his majestic surroundings – elsewhere the grandeur passes un-noted. Once in Amguid, the two set about searching for tombs and paintings; MM himself treks up the escarpment for a better look over the many crescent tombs he finds below but here, as later, he admits difficulty in getting a good photo of an entire structure when alongside it at ground level. It’s something I’ve found myself; they look so much more impressive on Google Earth or from a drone (left).

From Amguid they nip down in the rain towards In Ecker where they encounter stragglers on the second Abidjan-Nice rally (precursor to the Paris-Dakar). Then a diversion west takes them out past Silet for more tomb and rock-art spotting around the twin peaks of Tioueine.

There are more shopping difficulties, intransigent clerks and tedious permit apps on the lean streets of Tam (also my impression in ’82), then it’s off to Niger. On the piste down to In Guezzam I was surprised to read of the mass of crescent tombs the keen-eyed Milburn was finding, seeing as this was a well travelled route and I’d never heard of such reports from others. Perhaps most are too focused on getting to the other side. Google sat didn’t uncover much either, apart from a collection 140km northwest of In Guezzam as well as a few more a few kilometres northwest of the border post.

In Arlit there’s more admin to unravel before stocking up and setting out with Bazo, a Targui guide, to explore a region to the northwest of town. You suspect this may be a place Henri Lhote (of Tassili frescoes fame – often cited in SoSS) had reported on in the same year, and which may have been a revised destination for Milburn once his planned visit to the Western Sahara got nixed by the impending war. Accompanied by the agreeable and sharp-eyed Bazo, all sorts of fascinating discoveries are made in this little-visited part of the Aïr; it is the core of the book.

Like others I know, Milburn seems to be driven by an urge to uncover and classify and by doing so, understand. He shows an indefatigable enthusiasm for tracking down and logging these structures while speculating modestly on their origin and meaning, hoping that some day some pros will come down and do a proper investigation (those days seem long gone).
He then shoots off back to Tam, then returns south to spend time in the Laouni region north of In Guezzam with another guy and where, surprisingly, many more ancient discoveries are made among what you presume are the outcrops of Gara Eker. Then it’s back up to Tam and alone up to In Salah where he undertakes a dash over to Illizi via Amguid with some Germans, a stage that gets covered in a page or less. In Illizi they organise a camel recce of nearby Oued Djerat, the first Saharan rock art site to be well documented by Europeans back in the 1930s, and which Lhote had written about a year earlier.
That done, MM manages to drive some 600km southwest to Hirafok in a day in his 88” because the route north of Illizi was  closed and Tin Habedra to the west via Erg Tifernine was too sketchy alone. He then zips up to the Moroccan border, delighted to be out of Algeria, and a day or two later even more thrilled to be back in Spain. These last chapters end in such a rush when you think back to the protracted start of the book, you wonder if he’d suddenly exceeded a word count or ran out of time. A few weeks after writing this I was advised by someone who knows that: ‘… [SoSS] is deliberately misleading…’ as in, presumably, protecting new locations for later study.

So overall I was disappointed by what was an uneven read from someone who even then, had much experience of the Sahara, and has acquired much more since. It would be nice to think one day Mark Milburn may retire and write ‘Memoirs of a  Saharan Tomb Grader’. Among Brits he is rare and even appears to have a lighthearted edge judging by the picture left where he suggests the direction Land Rover should have taken.

The regular grumbling about lazy Spanish, sloppy Moroccan mechanics and any number of slack-arsed or obstructive Algerians, and not least his 88″, all get in the way of what must have been a great adventure and so should have been a better story. I was surprised to be unsatisfied by Secrets of South Sahara as a travelogue, but learned enough about the enigma of pre-Islamic tombs (as well as their very profusion, once you start looking)  to make it worth reading. It just reminds you how much more there is to see of the Sahara once you slow down and look closer.

mmairmanThe book has a few so-so photos; you’d think he must have come up with better; perhaps they were saved for other publications. The few graphics of tomb layouts are much better. The cover itself is a graphic of the intriguing ‘Air man with handbag’ which the author never saw, but mentioned that Lhote had found repeated over much of the Aïr. We ourselves found one at the popular site of Anakom (left) on the east side of the Aïr.
