Beaker Infants of Ifri n'Amr o'Moussa

Here's a quick paper from 2011 on two infants buried in a Moroccan cave.  They belong to the same group of individuals that are on the burials page.  (If you're on a portable device, you'll need to look for the page drop down from the top)

Absolute dating has not yet been performed as of 2012, but radiocarbon and luminescence dating puts layer materials prior to 3200 B.C.  The individuals don't have positively associated artifacts, but do belong to a Chalcolithic layer (Morocco is much earlier than Spain) which includes beaker fragments and copper artifacts.




I haven't seen the pottery fragments, but I would be surprised if all materials are the same age and are 3200.  On the other hand, we should not be surprised to see proto-Beaker materials since Beaker pottery has shown itself stubbornly non-evolutionary.  (It's difficult to draw a straight line since most of the techniques are increasingly present from earliest times in Portugal.)

The other issue here is the copper point which is either from a later period or the earliest attested (I suspect).  Again though, the CMP tradition came from somewhere and Morocco was comfortably Chalcolithic.  That artifact is another thing to watch.

Overall, these individuals are probably indeed pre-Beaker or early Beaker.  

There's another paper in the queue out there somewhere with absolute dating from a different Moroccan cave that should be out in several weeks.  It will be a later time period. I'll post as soon as I see it.

Danish Dagger Disovery - Once in a Lifetime

I believe this is probably a type II dagger, although the handle could be stitched under the grip.
Regardless, whether it's a II or III, it should fall within the 2300-1900 range.

It came out of a bog so the flint is probably stained to give it a darker obsidian look, but the news report clearly calls it flint.  Theoretically, if it is a type II or III it should be Chalcolithic (aka Early Brone Age) basically either a Beaker dagger or a people in communication with Beaker culture.
You can read about it at [Past Horizons]

Bog Dagger with Birch Handle

In a previous post [here]I expressed skepticism that these daggers were cheap substitutes for copper daggers.

While their form parallels the development of metal daggers, I don't know that I would necessarily call this imitation.  I would rather say that style changed regardless of its material composition.

Given the long history of Danish dagger making and the difficulty of finding suitable blocks of flint, I lean toward the idea that this is a distinct tradition rooted in the Late Neolithic and one that was maintained for nostalgic and practical reasons.


Nostalgia goes a long way.

"Apparent Cline" vs. "Real Cline"

To many, it is evident or probable that the paternal transformation of Western Europe is owed to the Bell Beakers.  There's not much room left for alternate candidates at this point given the growing stack of genetic studies from either side of the horizon.

It is comfortably demonstrable that the material culture of the Beakers emerged from Western Iberia.  It's not a global synthesis of a "bunch-o-cultures" and it's not a product of an archaeologically non-existent "unicorn culture".  Proper Bell Beaker culture congealed from a slurry of Western Iberian and North African influences.

However, when it comes to R1b, Beakers and Iberia, a lot of people have been getting mired into a seeming paradox (basically this map)>


Expansion of R1b (Michael Hammer)


Here's the fundamental problem with a Danubian R1b expansion (and this holds for the entire R1 family):  It is subtly predicated on the demic diffusion rate of a farmer's descendants as they sprawl at a rate of 1 km a year.  (Ammerman, Cavalli-Sforza, 1972, also 1984) or again (Pinhasi, Fort, Ammerman, 2005)

At this speed, sufficient time is allowed for branching in which founder twigs have time to move away from the base so that a cline is perceivable.  But we know R1b was absolutely not relevant in Europe during the Neolithic and we also know that the Bell Beaker and Corded Ware folks didn't expand at the Neolithic rate of 1 km a year.

Instead, their expansion rate was very rapid and absolutely involved folk movements (again, we are not yet swimming in genetic studies from pre-historic Europe, but at this point it is much more likely that they were exchanging spit rather than attractive pottery and new ideas.)

So what are we seeing in the map above?  Well, M269 is probably very old in the Middle East and its immediate periphery.  That's about it.

For argument purposes, let's say that the above picture accurately depicts a bona fide, demic cline of R1b movement from the Middle East through Europe.  What post-Neolithic phenomenon would explain the picture above?  Hold that thought...

Before you imagine metal-age, sword wielding barbarians riding chariots, carefully consider a diffusion rate that would give us a perceivable cline.  (in other words, takes-a-lot-of-time-for-mutations-to-occur-so-we-can-see-it-on-a-map)

The movements of R1a and R1b are going to be tough coconuts to crack.  Not only did these people move very rapidly, they are both characterized by regional super-lineages which are deceptive to their structure. 

It boggles my mind that there haven't been more testing at this point on Beaker cemeteries!

International Bell Beaker & Egyptian C-Ware Comparison

The Beaker Blog is on the archaeological road to hell.  The Apostasy continues.

Petrie Museum of Egyptian Archaeology UC14285

In the absence of any big archaeological news, I'll give a comparison of Egyptian White Cross-Lined Ware and early Bell Beaker International pottery.

I'm not going to suggest an especially close relationship between the two types, but rather suggest that a relationship is possible and that both typologies, being distinct from other potteries, fit into a stylistic scheme of the Central Saharan Pastoralist Societies.  (Read that carefully)





First, a few things about Egyptian White Cross-Lined (C-Ware).

C-Ware appears only very briefly in Egypt during the pre-dynastic Naqada IC sequence and probably last no more than a few generations to around IIA, possibly slightly overlapping the Gerzean period.
Naqada II probably heralds the arrival of Mespotamian invaders, at least it would appear so, whereas its predecessor, Naqada I, may involve a limited number of individuals integrating into Egyptian society from the Western Desert or the Southwest.

The latest absolute chronologies of the pre-dynastic era have been compressed to about 800 years and have shifted it to the right (Dee et al, 2013)  The exact timeframe in which C-Ware appears is sometime around 3600-3500 B.C.

Of the several daily-use pottery classes in Egypt, C-Ware is generally a mortuary ware and is found in the graves of about a third of the people.  Overall, the body of the ware is no different than the preceding Badarian and if fact, was probably made by the same pottery houses that made the former and common wares for centuries preceding.

The vast majority of C-Ware contains a scheme consisting of triangle, slashed-line and cross motifs, such as the beaker above, but occasionally animals and human figures appear of similar petroglyphic design of the Western Desert.  Curiously, great emphasis is given to the Barbary Sheep when non-abstract depictions occur.

Because C-Ware motifs are overlaid on previous pottery bodies, some of the symmetry can be awkward, which along with other archaeological indicators may point to disparities between scheme and body.  C-Ware is red slip burnish with contrasting white paint before firing, although some of it is encrusted with white paste.  C-Ware vases appear only later, but beakers comprise a third and dishes another third, usually one vessel per occupant (no information on sex distribution).

I've talked repeatedly about functional requirements within a design hierarchy in this blog.  Everything made by men, arrowheads or boats, need to do specific things in a certain order to satisfy his maker (with the assumption he is rational).  Factors may include efficiency, appearance, weight, material availability, etc, etc.

So typology can be a real pain in the ass because you can create a list of similarities between pencils and steak knives.  Deciding which similar traits weigh more than others can skew our interpretation of their genetic relationship.  So I understand that an argument could be made between Beaker ware and Corded Ware, and again the depth of the genetic relationship depends on what and how heavy we weight each factor.

Without further ado, here's some things that are similar between Beaker and C-Ware (and some differences).


1.  Both potteries are always red.  If you find a European beaker that is not reddish, either it is severely faded (usually) or it sucks at being a beaker (reasons vary).  The base coloration was extremely high in the design hierarchy.  Most potteries vary considerably in color - before, during, after.  These two follow strict conformance (regional soil dependent)

Achieving this was difficult for European Beaker potters due to the geology of Europe and in some cases resorted to painting it red.  It's clear, however, that an ideal beaker looks this>

2.  White line highlights contrast the base color.  This is usually done through encrustation with white paste in Beaker pottery, C-Ware is usually lined with white slip before firing (although sometimes encrusted).  The white paste may be hydroxyapatite (bone paste), calcium carbonates (lime) or in the case of Naqada, usually white clay.  The important thing to remember is that different manufacturing methods achieve the same result, so it is the result, not the habit, that is of interest.

3.  Triangle, zig-zag and cross motifs are the most common schemes.  C-Ware sometimes has less abstract depictions, as does Beaker ware, but C-Ware sometimes also includes animals and human figures.  Depictions of C-Ware tend to focus on the more elaborate or the odd, however most examples are more abstract.

Photography of both potteries tend to focus on the profile view.  What's lost is an important image often depicted on both potteries.  Many beakers have a white cross on the base, many C-Wares have a white cross in the bottom.

4.  It occupies a special significance in burial, and one that is apparently foreign to the more localized common ware.  The peculiar pottery is cohesive to a multi-regional identity and occurs in the graves of some people over a large geographical area who possess this identity.

4.  The two potteries appear with the dessication of the savanna (that became a desert).  C-Ware appears around 600-700 years before the first Maritime Iberian Beakers, but this number may yet be compressed with ongoing excavations.  It is also interpretation dependent.  If you look at the changes in Iberia's Late Neolithic and Kunst's writings on the motifs of the Iberian thick-rimmed bowls, it's entirely possible that the two phenomena appear at exactly the same time.

5.  Both potteries exhibit foreign elements and native elements within their respective regions.

Why is it more reasonable to believe that the immediate origin of the bell beaker is to be found 6,000 miles away (the steppe) and not a few miles away (Morocco)?
