Artwork deep dive: Helen Khal 'At the still point of the turning world'

This untitled work painted by Helen Khal (1923-2009) in 1969, features vast layered, faintly textured blocks of green. Details of this moderately sized canvas reveal steady, measured brushstrokes, built up to create hazy fields of colour. Dark green forms the breadth of this composition, fading into a rounded rectangle below, in a lighter, brighter green, glowing like painterly facets of an emerald.
