Stone spheres & archaeological placement
Develop a system from this study
Image note
Three original interpretations of stone spheres & archaeological placement, informed by Precolumbian Chiefdom Settlements with Stone Spheres of the Diquís. These images explore material and spatial ideas; they are not documentary views or measured reconstructions of the reference. The palette is drawn from the material portrait.

Image credits and reuseThe colour strip is the entry’s study palette. Artwork sources and image credits and reuse terms are recorded in the archive.
Artwork recordThree views of one material idea.
The Diquís sites preserve stone spheres alongside settlement remains. Their original purpose and production are not fully understood, making careful attention to archaeological context especially important.
Read the material study01 / Reading the material
The precision of a boundary
A stone sphere presents a continuous outline against an irregular setting. At the Diquís sites, that formal clarity sits within an archaeological context whose meanings are not fully resolved. Smoothness and geometry can be observed without claiming a particular symbolic explanation.

02 / From surface to space
Read the whole.
Then the edge.
Placement changes how a sphere is read: close to a boundary it can emphasize an edge; among other forms it can establish a centre or interval. Keep the recorded setting visible rather than replacing it with an invented arrangement presented as historical.
Compare the sphere’s smooth outline with the irregular ground around it. Study placement and scale without inventing a symbolic meaning.
03 / Colour in context
A palette you can work with.
Five tones drawn from the material portrait. Select a colour, compare it on paper and ink, or copy its value into your own study.

04 / At the bench
Make the observation tangible.
Place a plain sphere beside two rough planes and compare the negative spaces. Change position before changing colour. The aim is to study geometric contrast, while leaving questions of original purpose to the archaeological evidence.
Keep a view of the whole beside a close detail. Note the material, lighting and the one variable you changed.
