Maps, Stones & Plants: Agents of Empire and the Ecology of the Atlantic Trade

“The first step to understanding man is to consider him as a biological entity which has existed on this globe, affecting, and in turn affected by his fellow organisms, for many thousands of years.”

Alfred W. Crosby, The Columbian Exchange (1972)

As archaeologists across the world can affirm, human groups leave enduring traces of their labor and behavior in the sands and sediments of time.  Some of these traces are monumental in scale. Like the Great Wall of China or the Pyramids they are “written in stone.”  In fact, many of these structures are now visible from satellites in space.  By contrast, other traces are smaller than the human eye can see and can only be viewed through a microscopic examination of plant pollen and biological residues in topsoil and sediments.

The “Maps, Stones & Plants” display explores historical maps, drawings of plants, images of garden plots and people from the 18th century in conjunction with present-day satellite photography from space.  It invites participants to reflect upon some fundamental features of European maritime empires.

Questions that occur include:

  • How much energy (man-power) was required to build the stone forts in Africa that supported the Atlantic trade?
  • What was the source, quantity and nature of the food and water supply necessary to fuel all this work?
  • How were African agricultural practices and settlement patterns changed?  How were coastal, riverain, estuary, and forested ecosystems transformed with the arrival of new tools,  novel armaments and the unprecedented demand to provide manpower, food and fresh water for thousands of ships in the Atlantic slave trade?

As different cultures struggled to cope with the abrupt changes in the plant, animal and disease communities in which they found themselves immersed, what was the enduring impact of humans in the history of the trans-Atlantic world?  On one level, of course, all humans behave as a conscious species executing explicit plans with deliberate intentions.

But understanding these plans, intentions and conscious acts is not sufficient to account for human history.  The reason for this is that on another level humans as biological organisms also act as an unconscious vector-species in complex ecosystems, often completely unaware of the enduring impact of their immediate or long-term cumulative behavior.  This, too, can now be examined through the detailed ethno-botany and archaeology of the slave trade.

On a global scale, then, the “Maps, Stones & Plants” exhibit invites viewers to ponder some fundamental human questions from a new vantage point:

What is the human footprint on Earth over time?  That is, what is the role of human agency in Earth’s ever evolving ecosystems which we did not create, do not understand, cannot control, and must not continue to destroy?

This fort now exists as one of many built by the British and many other European trading powers along the Ghana coastline:

Because of developments in digital technology, large, monumental structures like these can now be viewed from space.

Further, because of the work of scholars and citizens around the world these structures can be “explored” virtually through a “street view:”

…from the ground level, from the outside…

…and from the “inside:”

The information captured through this kind of “virtual archaeology” can be quite detailed and revealing, posing a new series of questions to the viewer:

A sequence of historical maps of key islands off the coast of Africa are equally revealing.  See for example:

Goree-afriterra-2340

and compare this map with:

These maps can be linked to current material to provide greater depth to the understanding of the Atlantic trade.

    This is an online research and reference facility of for digital access to historical maps and other primary source materials relating to the study of Africa and its role in the world history from the late early-modern period through the nineteenth and early twentieth centuries.

  • Slave Voyages
    This is the most extensive international initiative for the systematic study of he slave trade in the digital age.  It has been undertaken by coordinated teams of historians, demographers, and social scientists that were funded from a series of research grants over the years.  The project is now hosted at Emory University in Atlanta, Georgia.  Data from the project in the “Trans-Atlantic Slave Trade Database”  currently contains records on over 36,000 individual slaving expeditions between 1514 and 1866, and it has been made accessible in various formats on the Internet.

This digital memorial raises questions about the largest slave trades in history and offers access to the documentation available to answer them. European colonizers turned to Africa for enslaved laborers to build the cities and extract the resources of the Americas. They forced millions of mostly unnamed Africans across the Atlantic to the Americas, and from one part of the Americas to another. Analyze these slave trades and view interactive maps, timelines, and animations to see the dispersal in action.
