I'm Emily Hart and today, I'll be speaking to two experts and campaigners on Colombia's San Agustín Statues – getting into what they might mean and why they matter, as well as how so many of them ended up not in Colombia, and how important it is to get them back here. In San Agustín, Huila, hundreds of ancient megalithic statues have been found, the region's largest collection of pre-Hispanic sculptures, dating back to the 9th century BC. Some are human-ish figures, but with fangs and wings, others are simian, some combination of animal and man - some are carved in situ, others onto single rock slabs 15 feet tall – the statues both invite and totally defy interpretation and theories about them abound, from burial rights, shamans, and psychedelic drugs to aliens. These statues were made by the Sculptor People, the Pueblo Escultor, an enigmatic community we are still trying to decipher. Surprisingly little is known about the people who created the mounds in which most of the statues were found – what they represent is much-debated, as is their purpose – the community also disappeared, moved away, or simply stopped sculpting well before the Spanish arrived – there are competing explanations as to why. Though there are hundreds of statues at archaeological sites around San Agustín, there are statues missing – in the 20th Century, European institutions and individuals removed statues from sites – many ended up in museums in cities like London and Berlin, others in private collections. But the movement to get this cultural patrimony back is gaining momentum – the current president has taken up the fight and hundreds of artefacts have been returned to Colombia over the last two years. It's a conversation which has been growing across the world – and the clamour from Colombia is being heard. The Colombian government has now officially requested the return of a number of these statues held in Germany, a big step for the campaign group to achieve the return the statues to their place of origin. There is, of course, also a San Agustin statue in the possession of the British Museum, which has not responded to attempts at communication. So, today on the show I have David Dellenback and Martha Gil, who are key to this campaign and will be telling us about the academic and ethical issues around repatriation, as well as digging into the history and lore of the statues themselves. David is originally from the US but has lived in San Agustín since the 1970s, author of the book 'The Statues of the Pueblo Escultor', along with the most complete set of diagrams and studies of the statuary, their measurements, locations, and features. Martha Gil is a guide and cultural activist, as well as translator of David's book into Spanish. The two, who are married, have presented the study, as well as an illustrated campaign book about the repatriation of these spiritual and cultural artefacts at Bogota's international bookfair, the FilBo. We are going to be talking about the ancient mysteries of the Pueblo Escultor and their megalithic language – as well as about the modern history of plunder and theft – and whether these perplexing statues might one day soon, be coming home.
