Today we will move across the globe to discover the Diquis Spheres. These are some stone spheres found in the delta of Diquis, between the rivers Terraba and Sierpe, in the peninsula of Osa and the Isla del Caño (Costa Rica). They are unique archaeological finds due to their number of existing specimens (over 300!), as well as their sizes, formations and rounded perfection. Their dimensions vary from the 10 cm to 2.57 m of diameter. They can weigh as much as 16 tones and have been found in 34 different archaeological sites. These are the products of the Diquis culture: a pre-Columbian culture, indigenous from Costa Rica. Diquis means great waters or river in the Boruca language (the native speaking tongue), which seems to tie in with the locations of the finds. However, their meaning and origin is a mystery.
According to Ifigenia Quintanilla (University of Costa Rica), the spheres were most likely produced sometime between the 800 and the 500 B.C. However, local archaeologists investigating the subject have trouble dating and interpreting them as 90% of the spheres have been moved and found away from their original locations. The theories on their meaning and purpose get even more obscure and confusing. Most archaeologists and historians support the idea that these artifices had an astronomical function. Perhaps they were a way of timing agricultural cycles, or even maybe representations of constellations. Another supported hypothesis is that these could be used as markers of social status for the leaders of the indigenous tribes. Nevertheless, more fantastical explanations have been proposed:
-Some think these could have been done by the people of Atlantis, or even by extra-terrestrial beings!
-There is also the myth that the Diquis culture knew of a chemical product that could manipulate the physical state and shape of stone.
-Some more logical beliefs consider that perhaps these were used as territorial markers.
-More interestingly, many have found them to be an analogy of a pre-Columbian myth. This is related to the god of thunder Tara, or Tlachque, who used throw some spherical objects against the Serke, or the gods of wind and hurricane, to keep them away from these lands.
The Diquis Spheres in Modern Day Costa Rica:
The spheres were discovered in 1939 when the American company United Fruits made some moves over Costa Rica in order to clear some woodlands for the sake of banana cultivation. And then the mystery and fascination began.
They were first mentioned, and worthy of scholarly consideration, in 1943 when Doris Stone wrote an article for the magazine American Antiquity about them. Since then, many studies have been carried out to try to understand what these items actually are. And it seems that one of the most plausible explanation is that these spheres were used as some form of astronomical tool (Ivar Zapp, George Erikson, 1998). Other theories, such as the work produces by Patricia Fernandez and Ifigenia Quintanilla support the idea that these were public items; symbols of local power (2003). Perhaps this ties in with the theory that the stones were actually used by this society for funerary purposes, and that although no clear dating or chronology has been established yet, the society that produced them were likely to be a splinter group from the Aguas Buenas settlement (Roberto Herrera, 2017). This makes sense if we consider, as pointed out by some of the most striking pieces of goldsmithing does come from the Diquis area as well.
However, the research moves slowly. It took years for scholars to actually show a decent interest in the subject and try to solve the mystery. It seems that for several decades, the spheres lied out in this banana plantation, forgotten, catching the interest of occasional looters. Nonetheless, these stones are part of the collective memory of Costa Rica. They are a symbol of identity for the indigenous and local inhabitants, and they are commonly referenced in their popular culture and the media. Thanks to the superb work of archaeologists Francisco Corrales and Adrian Badilla (Museo Nacional de Costa Rica) since 2002 to the area has gained some interest, to the point that, it is worth mentioning that the Diquis spheres have as of 2014 – a year after the original introduction to this piece was written – now been added to the UNESCO World Heritage Site, and the site, tourism and conservation of the area evolves slowly as this is a new field for the Costa Rican nation.
We can only hope that the new generations of archaeologist will bring us more answers as to the origin and faction of these items, and of course, how they were made!
