REMARKS ON THE SAHARAN HEEL-SHAPED CAIRN
During summer 1975, the writer's attention having been drawn to Scottish
heel-shaped cairns ( "HSCs"), it was resolved to re-visit certain Saharan sites, as well
as keeping a sharp lookout for others. As a result it has been possible to compile a
short list-probably in no way representative of true total dispersion-indicative of
the wide geographical distribution of constructions whose siting, orientation and
overall similarity of plan enables them to be termed HSCs. Dating of the Scottish
monuments, both in the Shetland Islands and on the Mainland, being as yet
problematical (Henshall, 1972, 286: 1974, 162), we are no more fortunate with
Saharan specimens. French nomenclature is complicated by a bewildering array of
intermediate types, some of which are neither the V-shapes nor crescents shown by
Monad ( 1948, 26) in West Sahara, nor yet the Haggar crescents-no less than six
varieties-cited by Denis (1959, 296). The latter's top centre monument (Fig. 1) is
somewhat similar in plan to Ward of Symbister Ness which, in Saharan terminology,
ranks as a crescent. Compare also Woisard (1955, 158).
No one has yet recognised the existence of HSCs outside Scottish territory nor
has the writer been lucky enough to sight a single French or Spanish excavation
report for any construction here tentatively labelled as such. The present remarks,
therefore, must sufice only to record some common features of Scottish and African
cairns, in the hope that ever-improving scientific techniques, especially in the realm
of dating, may enable investigations to be taken further at some future date.
Saharan HSCs (and, of course, crescents, V-shapes and constructions with arms
(or "monuments a bras" in French) tend to be sited on east-facing forward slopes,
atop knolls and even in open flat terrain with a good view ahead. They may be placed
across a col (Camps, 1974, Pl. XX, 2.) in the Western Haggar, a seemingly rare
occurrence also noted by R. Letan in the Moroccan Sahara and later shown to the
writer. Whole "fields" of crescents are not uncommon, at least in Central West
Mauritania, in South Central Algeria between Tamanrasset and In Guezzam, as also
in the Western A"ir zone of Niger, to judge only by personal observations.
While Henshall remarks (1963, 148) that the orientation of Shetland cairns is
notably consistent in a preference for the south-east, it appears too early to profer a
similar orientation in respect of the Sahara; it is however probable that a
predominant heading of between north-east and south-east may prove to be the rule,
always assuming that the numerous west-facing crescents of the far south of Algeria
and Western /\ir (Milburn, forthcoming) do not turn out to possess similarly
eccentric relations classifiable as HSCs. However, the orientation of those monuments
usually considered as being archaic (Camps, 1970, 239: Mauny, 1961, 88:
Milburn, 1976, 3 ), being composed wholly or partially of flat paving sometimes
surmounted by a tumulus (French: "dallages"), is believed to lie invariably within
the eastern half of the compass.

Since the list below attempts to compare the plan of each Saharan example with
that of at least one named Scottish site, there are certain additional features worthy
of note in passing. There can exist a larger stone or stones at the tips of Saharan
crescents (with two observed cases for HSCs) whose function can only be described
as architectural embellishment, unless the construction happens to stand on a steep
forward slope. This should not be confused with the Saharan practice of placing
three stones, in triangle pattern, at the tip of one arm only (Bessac, 1953, 1603), in
North-western Africa, whose purpose is still unknown. The former custom (Fig. 2)
is, however, suggestive of a tradition of the Scottish "upright stone" or "pillar
stones" at the extremities of the fas;ade (Bryce, 1940, 25, 28, 32).
Regarding mounds of stone placed before the front of Shetland facades,
presumably intended to convert the HSC into a round one (Henshall, 1970, 44 ), it
was noted that the Saharan site south of Gara Tesmad possesses a scatter of stones
just in front of the centre of the facade. And a seemingly-local feature of the
orientated monuments around Hassi el Khenig and Guelta Tiguelguemine, with one
example also in Oued Tiguelguemine, consists of small stones piled up right on the
"brow" of the construction, just behind the border of the fai;:ade and contiguous;
the zone covered is often not more than about two metres square. So far it is not
intended to attribute any special significance to this Saharan feature, which may
well prove to be wide-spread, although apparently unpublished. One platform cairn
("PC"-thanks are due to Miss A. S. Henshall for this nomenclature) two kilometres
south of Hassi el Khenig, to west of the main track, has a small stone pile six paces
outside its eastern border; it is not known whether this is a later addition. Reygasse
(1950, 72) reports finding a lone skull in a similar construction in Western Haggar,
describing it-as have other French authors-as a stone circle.
A further Saharan custom-that of prolonging one or both of the tips of a
crescent into long thin "tails"-does not occur to date in the few 'cairns seen;
nonetheless certain aerial photographs of parts of North-west Sahara, plus personal
observation in such widely-divergent zones as Choum (Central West Mauritania) and
In Guezzam (frontier of South Central Algeria with Niger) indicates a large area of
dispersion of this practice. Near In Guezzam in January 1976 the writer logged a
distance of around 280 paces, from the centre of one crescent to the apparent far
end of its southern tail, without being able-as yet-to ofer an explanation for this
spectacular phenomenon.
The most succinct excavation report yet observed, which concerns a crescent
rather than a HSC, is that given by Mercer (1976, 67). A crescentic tomb dug on
Cape Blanc (Mauritania) by a French schoolmaster had a small entrance leading into
a domed corbelled chamber: a crouched skeleton lay on the ground. For the benefit
of readers outside Scotland, there is every reason to hope that further examples of
HSCs will turn up on the Scottish Mainland.
I thank P. J. M. Geelan, Professor E. T. Hall, Miss A. S. Henshall, J. Mercer and
Professor Th. Monad for various information and communications, all of which have
proved invaluable in compiling this short resume. Only bare outline plans of Scottish
HSCs are given, based on those of Miss Henshall.
