Technique and condition
The painting was executed in artists' oil paints from Spectrum Oil Colours, thinned with mixtures of white spirit and linseed oil. The quantity of oil in the painting medium was increased as the work progressed to reduce the likelihood of excessive 'sinking' of the top layers of paint.
The left canvas was painted first, beginning with a globe like image in the centre which evolved into the present image, the right canvas being added later. Covering a whole wall in the artists' studio, the two canvases created a mural like effect lit from the left. Applied broadly in many layers of broken brushwork, the paint is scumbled over previous work, scraped back and reworked wet-into-wet. The left canvas, being the first started and closer to the light source in the studio, is more extensively worked than the right.
The painting is not varnished, retaining the variety of surface variations which are essential to creating the subtle effects of depth and recession. It is not framed, leaving the messy edges of the canvases clearly visible which emphasise the appearance of the painting as a 'tablet of colour'.
