The theory excitingly drew on similarities in the abstract patterns of the Indian art in Peru, including the famous Nazca lines the art of the Tukano societies of the Colombian Amazon region the yarn paintings of the Huichol Indians in Mexico, the so-called “grecas” of North American Indian art and in the art tradition of Australian Aboriginal Dreaming. All humans, experience similar images and vortex-like tunnels, sometimes followed by a similar level of immersion in a wholly ‘other’ visionary realm of hallucinations. Their theory in a nutshell was that, due to hard-wired neurophysiology, various stages of altered states reveal similar geometric shapes (entoptic phenomena). David Lewis-Williams and Thomas Dowson observed that the rock and cave art of the later Paleolithic (about 40,000 to 10,000 BC) coincided with the time when homo sapiens had developed abstract thinking and that the art was characterised by both vivid depictions of animals on the one hand (the hunt) and geometric figures such as dots, circles, lines and curves (the dreaming) on the other. In 1988, two South African archaeologists referred to entoptic images when they presented an alternative interpretation of stone age rock art of a certain kind. Research as early as the 19 thC showed that entoptic phenomena could be manipulated by selectively induced changes to conscious states and as a subjective light phenomena they had become – amongst some more spiritually-minded researchers at least – a means to explain the genesis of the abstract imagery found in shamanistic art. Some may be individual swollen red blood cells or chains of cells stuck together or a mix of the proteins of the vitreous gel with embryonic remnants. They are shadow images of objects suspended just above the retina. It has been posited that the dots before our eyes, the harmless vitreous opacities or muscae volitantes often called ‘floaters’ are a primary source for the constellation of archetypal forms that lie at the root of symbolic art in cultures across the world.Įntoptic images are slowly drifting blobs, lines or striations of varying size, shape, and transparency, which are particularly noticeable when viewing a bright, featureless background – such as the sky – or a point source of diffuse light very close to the eye. Sometimes the journey takes you in unexpected directions. ![]() For me the entoptic images came first, and the, somewhat exotic, theories surrounding them came second. And recently it drew me to entoptics, where symbolic forms seemed to readily express for example, journeys, land-forms or weather formations. ![]() It’s an enterprise that has taken me in search of a symbolic vocabulary able to express, in non-verbal terms, my obsession with connections/history/belonging /boat/place/time/earth-air-fire-water/shelter etc. Amongst the clutter lying on the Museum floor are many attempts, on my behalf, to create artworks based on the narrow boat water can. My research into, and celebration of, the narrow boat man’s decorated water cans can be found hereor here. In the Museum of Thin Objects stories co-exist – just as they do in the rest of life – as a complex and often unfinished expression of the world around us. Because of the variation between individuals, and the inability for two observers to share a nearly identical stimulus, these phenomena are unlike most visual sensations.Structuring, making something coherent out of the chaos of the natural world, is the essence of being human. This variance is not surprising because the specific aspects of the eye that produce these images are unique to each individual. ![]() Helmholtz comments on phenomena which could be seen easily by some observers, but could not be seen at all by others. Because entoptic images are caused by phenomena within the observer's own eye, they share one feature with optical illusions and hallucinations: the observer cannot share a direct and specific view of the phenomenon with others. ![]() Hence, they are different from optical illusions, which are perceptual effects that arise from interpretations of the image by the brain. These perceptions are called entoptical." Entoptic images have a physical basis in the image cast upon the retina. In Helmholtz's words "Under suitable conditions light falling on the eye may render visible certain objects within the eye itself. Entoptic phenomenon Entoptic phenomena are visual effects whose source is within the eye itself. ![]()
