New discoveries of cave art in the Caribbean

New cave art discoveries in the pre-Columbian CaribbeanJago Cooper, curator, British Museum

At the end of May, I returned to the British Museum from an exploratory research visit to an uninhabited national park on the island of Mona in Puerto Rico. My colleague Dr Alice Samson, McDonald Institute for Archaeological Research, and I had found more than we planned or expected when we flew to the Caribbean two weeks earlier.

There are hundreds of caves on Isla de Mona many with entrances like this one on cliff faces overlooking the coastline below.

Alerted to the potential presence of archaeological sites dating to the pre-Columbian period (prior to AD 1492 when Christopher Columbus first arrived in the Americas) by National park manager Tony Nieves, we went to take a look. We discovered extensive pre-Columbian mining and artistic practices deep inside caves, with an astonishing abundance and diversity of new rock art including pictographs and finger-incised designs representing abstract, human and animal images.

The pre-Columbian iconography found in many of these cave systems extends through galleried chambers covering large portions of the walls and ceilings.

Designs, which cover the walls and ceilings of hundreds of metres of the darkest caverns and tunnels across the island were executed by the application of pigments to cave walls, and by previously undocumented techniques such as incising and dragging fingers through the very soft, plaster-like deposit on the cave walls. This particular technique left white trails of surprising freshness, complexity and elaborateness.

Many of the representations are clearly identifiable. This figure with the swirling arms represents Guabancex, the pre-Columbian deity associated with the destructive force of the hurricane.

Strikingly the technique also appears to have been a way of harvesting the soft deposit on the cave walls as is attested by the vigorous finger scratching across large expanses of cave surfaces in all of the sites we visited. These extractive activities, or evidence for ancient mining, rather than being indiscriminate movements, were systematic and deliberate actions leaving complex designs.

This figure is identical to the famous Puerto Rican Sol de Jayuya rock art image found in central Puerto Rico.

Alongside Dr Samson I’m working in collaboration with the Department of Natural and Environmental Resources and the Institute of Puerto Rican Culture to develop a project to study the pre-Columbian archaeology of the island and protect this unique Caribbean heritage. Many of the caves we explored have not been visited since guano (essentially bat excrement, a very effective fertilizer) miners working there downed tools 120 years ago, leaving the ruins of railway tracks, wagons and sometimes their initials on the cave walls.

The caves are incredibly well preserved sites, but are at very high risk of future destruction due to the soft texture of the walls and confined spaces for visitors to gain access. A glimpse of this archaeology is shown in our project gallery page.

The evidence we found not only dramatically expands our repertoire of pre-Columbian iconography, but has the potential to change understandings of past cave use in this area at this time, as well as traditional definitions of rock art.

The fieldwork discussed in this blog was consequently reported in detail at the International Association of Caribbean Archaeology in San Juan, Puerto Rico on 17 July 2013 and more information can now be found on the Antiquity Journal website.

To celebrate our partnership with @googleartproject, we’ve asked members of British Museum staff to highlight their favourite objects and explain what makes them special. Jill Cook, Deputy Keeper of Britain, Europe & Prehistory, chose this stone chopping tool from an early human campsite in Olduvai Gorge, Tanzania. ‘Holding this 2 million year old African tool in my hand I am reminded that whatever differences exist between people now, we are united by our common origin in Africa. The discovery of this piece by Louis Leakey in 1931 began to change our understanding of what makes us human. It illustrates the beginning of a transition from an ancestral ape that walked upright on two legs within the confines of a limited ecological niche to humans with more complex brains capable of changing and eventually dominating the world around us by making tools and weapons. This chopping tool is one of the seeds from which all human cultures and societies have grown.’ Discover the stories of thousands of objects in the Google Cultural Institute at

#MuseumOfTheWorld In Victorian England many people were fascinated by their past, and the ancient tribal leader Caratacus (also spelt Caractacus) was adopted as a symbol of national pride and independence. Like Boudica, Caratacus resisted the Roman invasion of Britain. Although he was eventually defeated, he earned a reputation as a noble and worthy foe. The Victorian sculptor J H Foley portrays him here standing triumphant, the embodiment of courageous English spirit. See this incredible #Movember moustache in our #Celts exhibition, until 31 January 2016.
J H Foley (1818–1874), Caractacus. Marble, 1856–1859. On loan from Guildhall Art Gallery/Mansion House, City of London. Some more #Movember inspiration! Here’s the Museum’s security team from 1902 photographed on the front steps. They include officers from the Metropolitan Police, and the London Fire Brigade (identified by their flat caps). We’re celebrating #Movember with Museum moustaches great and small. Here’s a #Movember fact: Peter the Great of Russia introduced a beard tax in 1698 and this token was given as proof of payment! Our unique new partnership with Google's Cultural Institute @googleartproject now allows you to virtually walk through the whole Museum! The British Museum is the largest space ever to be captured on indoor #StreetView, putting the unparalleled world collection at your fingertips. Come and explore!
#MuseumOfTheWorld #Google #ForEveryone Have you explored the Museum on @googleartproject yet? You'll now find over 5,000 objects in the Google Cultural Institute, including virtual exhibits inspired by #Celts and #EgyptExhibition as well as gigapixel imagery and the whole Museum on #StreetView!
