Photoshoot with Warren King Photography resulted in some great images of my work ready for the press release and promotion of A STONE SKY – the upcoming joint exhibition, with Julie F Hill, that we have been working towards for many months. The exhibition will be at Thames-side Studios Gallery 11th – 26th November 2023 with a private view on 10th November 6-9pm.

A Stone Sky brings together the works of multi-disciplinary artists Julie F Hill and Susan Eyre who traverse cosmic layers from the deep earth to deep space, exploring manifestations of darkness and its associations with the unknown and undiscovered. Reimagining the idea of an observatory, their sculptures and installations reach for scales and orders that surpass the human, revealing the cosmic at our feet. The exhibition proposes a cavernous realm of real and speculative possibilities that arise from beyond the limits of human perception. Engaging with the extended sensory range offered by technologies such as orbiting space telescopes through to the ability of birds to ‘see’ the Earth’s magnetic field, the artists’ reveal intimate connections between earth and space.
It was great to meet Anjana Janardhan who we have commissioned to write an essay for a publication which will be launched on the final weekend of the exhibition. We are also planning to give some informal readings, tours of the work and I will be running the cloud chamber so visitors can see the trails of cosmic rays – a way of visualising these unseen visitors from the stars.
The Azimuth Obelisk (of sedimentary knowledge) sculpture is an almost 3m tall reimagining of the obelisk erected at Hartland Magnetic Observatory in 1955 as an azimuth mark to be viewed from the Observing Room or Absolute Hut to monitor the drift of the magnetic north pole.
I have obtained an old wooden trolley to put the cosmic ray detectors and projector on for the digital video work The Breath of Stars. This feels in keeping with the original furniture used at Hartland Magnetic Observatory. The Breath of Stars directly interacts with cosmic rays – as each cosmic ray particle strikes a plastic scintillator its energy is recorded and a starburst image video is projected. The interaction of cosmic rays and the solar wind with atmospheric electrical fields combines to influence the unpredictability of the magnetosphere. Most radioactive particles heading for Earth are deflected by the magnetosphere. Without the Earth’s magnetic field deflecting the majority of cosmic rays, life on this planet could not survive.
The 48 paper tiles for the roof of The Absolute Hut (of action potential) are made using the suminagashi technique of marbling with a colour to reflect both the sky and the patinated copper roof tiles of the Observation Hut at Hartland Magnetic Observatory. The paper is Japanese Osho Select and is very fragile when wet so has to be pulled from the water tray using a supporting mesh. Topological contours of suminagashi marbling reflect the fluid motion of the Earth’s magnetic dynamo and the pulsating alpha waves of the human brain when subjected to magnetic fields.
If you place a polarising filter over a screen that emits polarised light and use a polarising lens on the camera, then any plastic, photographed in this method, especially injection-moulded plastic, reveals stress points with a kaleidoscope of colours known as birefringence. Cryptochrome, the protein molecule found in a birds eye that enables birds to ‘see’ the magnetic field is excited by polarised light. Polarisation may also reveal the existence and properties of magnetic fields in the space medium light has travelled through. Research suggests that human alpha brainwaves react to a changing magnetic field. These ideas are brought together in a video work speculating on human magnetoreception via magnetite crystals in brain cells.
This video work will be shown on multiple small screens inside The Absolute Hut (of action potential) alongside two larger monitors showing companion video pieces exploring dynamics between the Earth’s geologic structure and navigation using the magnetic field.
I have replicated the experiment I saw at the National Physical Laboratory, dropping a magnet down a copper pipe to see how the magnetic field generated slows the magnet down considerably. I filmed this and added a tiny led light with the magnet.
Finally dark skies and fine weather coincided so I was able to go and make a time lapse of the stars rotating around Polaris.
Instruments of the Anemoi is a set of three dodecagon tablets cast in Snowcrete, a non-magnetic cement, as used in a magnetic observatory. Suggestive of the pedestals that support various instruments used in monitoring the Earths’ magnetic field they also respond to an ancient anemoscope “table of the winds” inscribed with the Greek and Latin names of classical winds on each of its twelve sides.
Hand cut copper pieces to be etched with images based on associations and attributes of the twelve Greek wind gods.
Sugar lift solution is screen printed onto the copper pieces.
These are then dipped in bitumen and immersed in hot water where the sugar slowly dissolves to reveal the image.
They are then left to dry before being etched.
These were etched for 2 hours in an Edinburgh Etch solution, made with ferric chloride, citric acid and water to get a deep etch. The detail in the bitumen held very well. I constructed a collagraph from card to attach them to for casting in concrete. Once etched the detail areas were painted with a soy sauce solution before being placed in an ammonia vapour bath.
After a few hours patinating they are removed to dry before being cleaned up.
Positions are marked out on the collagraph and double sided tape is used to secure the pieces in place face down. The collagraph is then placed in the silicon mould ready for casting with Snowcrete – the same non-magnetic concrete used at a magnetic observatory.
This is the third of the tablets to be cast for the work Instruments of the Anemoi. The first holds a copper bowl with a ‘silver fish’ floating in water based on the oval shaped compass needle (illustrated in Breve Compendio de la Sphera de la arte Navegar by Martin Cortes 1551) as symbol of the silver fish – wafer thin fish shaped iron leaves used by 11th century Chinese geomancers.
The second has embedded magnets in a pattern revealed by old nails and iron filings over the surface. One legend on the discovery of the lodestone recalls a Greek shepherd who noticed the nails in his boots were attracted to the lodestone (also known as magnetite a naturally occurring mineral).
The tablets will be shown on adapted wooden theodolite or telescope tripods in the spirit of equipment seen below during my research trip to Hartland Magnetic Observatory.
Gallery Visits
Seismic Mother curated by Charly Blackburn and Holly Birtles at Hypha Space – an exhibition of 20 artists whose work attempts to communicate the seemingly incomprehensible nature of the earth’s magnitude and magnificence, temerity and resilience as it endures, regenerates and struggles to survive through the slow violence of ecological catastrophe. I visited for the book launch and performative reading from Stephen Cornford whose book, Petrified Matter, I bought. It’s an enlightening read on the links between photography and fossils through mineral, chemical and data recording processes, going on to speculate on future geology and the impossibility of reversing the extraction process by separating minerals used in mobile phones and other technology to return these back to the soil.
