EVERY which way: Geometric forms, a drawing in charcoal and chalk on brown paper, by Gordon Froud. Photograph courtesy Total Exposure.

AS YOU ENTER the upstairs space, courtesy of the architects of the Standard Bank Gallery, there’s an implicit sense of event. This is obviously always the case. But it’s enhanced several-fold in Gordon Froud’s first major retrospective. How? Curatorial decisions have dramatically place a massive polyhedron in your face. This exhibition is about time – but it’s also all about space and geometry and God.

But ah! you might cry, as you summit the staircase, this polyhedron is stumped. It’s got blunt points. It’s dramatic, sure, but there’s something artisanal about it. And then you step a little closer and look at the tessellation wall works, which surround said polyhedron. They may you feel as though you have stepped into a child’s kaleidoscope on crack. And then you realise they’re made of black plastic coathangers and cable ties, and the blunt edges of the polyhedron are appropriate because the whole object is made of giant traffic cones. It is then that the world begins to turn on its axis for you as you engage with this extraordinary exhibition.

Mooted as a mid-career project, this exhibition sees Froud in his mid 50s, offering sophisticated and carefully articulated summation on all that he’s been working on and interested in through his career. And while the geometry is central to it all, there’s an ethos as to where this geometry is found and how it is extrapolated that keeps you curious to the very end.

But more than that, Froud takes the whole of the upstairs gallery space and uses it with clarity and empathy. It’s a humble exhibition that is about the real skills of looking and drawing on supports such as brown paper, but a proud one too, that examines a great diversity of artmaking approaches. Ultimately, it is satisfyingly balanced in the layout of work, which takes you through four ‘chapters’ of possibility.

You do, however, emerge from this exhibition remembering Froud’s fondness for all things Alice in Wonderland.  Not because there’s a Cheshire Cat secreted in the interstices of the lines and circles here, but rather because the mathematical ethos of Lewis Carroll’s madcap ideas are spun under the surface of these works.

And while as a body of work it touches on everything from Jewish to Christian to Hindu to Buddhist splays of spiritual values, it also doffs a cap to Leonardo’s thinking and sees a spot of geometry in the world as it stands. In doing so, it evokes the thinkings of György Doczi on proportional harmonies in nature and everything else.

That said, a couple of series in this exhibition, including the photographs of the figure in geometry, feel almost too diagrammatic and if you’re not in the know in terms of mystical values, they may leave you cold. Similarly, a series of embossed images toward the chronological closure of the show feel so busy that you cannot look at them. But Froud is an interesting character and this exhibition really does go the extra mile in offering something for everyone. It’s astonishing to acknowledge that all of this is the work of one artist.

And further to everything, this society has a troubling relationship of not being able to celebrate its own. For whatever reason. Often an artist needs to go overseas and earn ticks from the so-called “International community” before he or she gets a nod from local establishments. Froud’s show here and now kind of bucks this trend, but for a mid-career show to be mounted in the latter years of as prolific a practitioner as he, feels uncomfortable. However, as you walk through the four chapters of this exhibition, so do you realise that this is most likely where serious fine art in contemporary society is pointing right now: the invested thought. The carefully drawn line. The gesture that is unashamedly analogue. This is an important show for all the right reasons.
