Summary:
Rising as high as 20 feet, ancient stone monoliths in southern
Ethiopia are 1,000 years older than scientists previously thought,
according to a new study. A research team used advanced radiocarbon
dating to determine the often phallic-shaped monoliths, or stelae,
at the Sakaro Sodo archeological site in Ethiopia's Gedeo zone
were likely created sometime during the first century A.D.



FULL STORY ========================================================================== Rising as high as 20 feet, ancient stone monoliths in southern Ethiopia
are 1,000 years older than scientists previously thought, according to
a new study in the Journal of African Archaeology.


==========================================================================
A Washington State University research team used advanced radiocarbon
dating to determine the often phallic-shaped monoliths, or stelae, at
the Sakaro Sodo archeological site in Ethiopia's Gedeo zone were likely
created sometime during the first century A.D.

The only other attempt to determine the age of the more than 10,000 stele monoliths located at various sites in the Gedeo zone was conducted by
French scientists in the 1990s. It provided a far more modest construction
date of around 1100 A.D. for the monuments of Tuto Fela in the northern
part of Gedeo.

Under consideration as a UNESCO World Heritage Site, Sakaro Sodo and other archeological sites in the Gedeo zone have the largest number and highest concentration of megalithic stele monuments in Africa. The standing
stones range widely in size, function, and arrangement in the landscape.

While many of the monoliths have fallen and/or are undecorated, a few
have intricately wrought faces and other anthropomorphic designs carved
into the stone that can be seen today.

Despite the impressive nature of the archeological site, little is known
about why or how the monoliths were built.



========================================================================== "This is one of the most understudied archaeological sites in the world,
and we wanted to change that," said Ashenafi Zena, lead author of the
study and a former WSU doctoral researcher now at the State Historical
Society of North Dakota.

Zena, an Ethiopian native, originally decided to conduct a study of the
stones after traveling to the region with his doctoral advisor Andrew
Duff, a WSU professor of anthropology, in 2013.

"It was shocking to see such a large number of monuments in such a
small area," Zena said. "Looking at the stones, many of which had
fallen to the ground and some have broken into pieces, I decided to
focus my dissertation work there instead of investigating cave sites
in southern Ethiopia." In addition to pushing back the date of the
earliest monoliths' construction by a millennium, the researchers also determined where the ancient builders of the site likely quarried raw
stone for the project. They also identified, for the first time, the
earliest known sources of obsidian artifacts that were recovered from
the Gedeo stele sites.

Surprisingly, most of the obsidian the researchers identified at Sakaro
Sodo originated some 300 km away in northern Kenya, illustrating that
the people at Sakaro Sodo obtained most of their obsidian raw materials
through some form of exchange or trade.



========================================================================== While little is known about the pastoral and/or agricultural people who populated the Sakaro Sodo region of southern Ethiopia at the turn of
the first millennium, the new construction dates of the stele monuments identified by Zena and Duff appear to coincide with the arrival of
domesticated animals in the region and the beginnings of more complex
social and economic systems.

"One of the reasons why this research is important is because it has
the potential to shed new light on what the earliest people in this
area were doing for a living as well as what their cultural and social practices were," Duff said.

Existing archaeological, ethnographic, and living megalithic stele
traditions in the region suggest that the oldest stele sites in Ethiopia
at Sakaro Sodo and other nearby locations were likely created for two
purposes: to commemorate the transfer of power from one generation to
the next or to record and commemorate group achievement.

"The diversity of function of the stele in Ethiopia is really
fascinating," Duff said. "For example, we know that the more recently constructed stele monuments of Tuto Fela in the north part of Gedeo were
used as burial markers.

While the linear placement pattern of the earliest stones at Sakaro
Sodo makes us think they may have been markers to signify the passing
of generational leadership." While the political situation and the
recent escalation of the COVID-19 pandemic in Ethiopia make following
up on the investigation in the near term difficult, the researchers have several future projects in the works that they hope to continue as soon
as possible.

One project involves more additional archeological investigations at
other stele sites in the areas with colleagues at Addis Ababa University
in Ethiopia.

The other is a project led by Duff and current WSU doctoral student
Addisalem Melesse who are working with the Ethiopian Department of
Archeology and Heritage Management to determine how the stele sites
can be better managed to both preserve the heritage of the region and
generate tourism.

"Developing a better understanding of the function of these stones and
how they were erected is really useful in terms of gaining a UNESCO World Heritage designation," Duff said. "This could in turn help generate
tourism revenue, which is a major economic factor for the country." ========================================================================== Story Source: Materials provided by Washington_State_University. Original written by William Ferguson. Note: Content may be edited for style
