ACCORDING to the 18th-century French political philosopher, Charles, Baron de Montesquieu, if triangles invented a god, they would make him three-sided.

After seeing Simple Matters at The Exchange, Penzance, there's every chance they would name that god after its creator, George Meyrick.

He has used a dozen variations of that triangle, from a Suspended Corner Drawing to a Horizontal Wedged Drawing.

They add up to what is essentially an installation with which he reworks that shape in response to the architecture of the gallery.

There is colour here which not only adds to the elegance of his geometric shapes but also increases the impact upon the viewer. From his central Two Forms, drawn in coloured cord and comprising two identical forms, one spatial, aerial and light, the other tight, objective and densely material, to his exploration of Inside The Outside, from flat painted areas to those triangles that seem to sprout from the walls, not forgetting the presence of optical illusion, the interplay of actual and implied forms, he certainly. intrigues.

An artist with a national and international reputation, born in London but who has lived and worked near Camborne, for the past three years or so, George Meyrick has exhibited extensively from Kettle's Yard, Cambridge to the Henry Moore Institute, Leeds, and throughout Europe. The Henry Moore Institute holds all his early sketch books and maquettes in its archive. His student drawings, consisting of wooden rods and their shadows thrown by a light source, had an elusive quality still evident in his current work. Solid triangles intersect corners or emerge from the surface of a wall and combine with an apparently three-dimensional form which is actually a piece of flat painting. Admission is free, and George Meyrick's Simple Matters can be seen in The Exchange, Princes Street, Penzance, until April 14.

A seminar on The Art of Making, inspired by Meyrick's exhibition and that of work by Breon O'Casey is being held in Newlyn Art Gallery on April 7. This is free, but advance booking is essential. Also at the Exchange, each Wednesday, 6pm to 8pm, February 29 to March 28, there is 3-D Thinking led by Patrick Lowry. £12 per session, advance booking essential. During half-term and the Easter holidays there are DIY Make and Do Free activities, inspired by Meyrick's fantastic forms.
