Ever since medieval engineers discovered ways to open up the stone walls of their cathedrals, architectural glass has been among the glories of Western imagination.

The glass has not always been coloured. Classical Revival architects in the Renaissance wanted their churches and residential interiors lit by clear windows. The pioneers of architectural modernism followed suit — hence the handsome expanses of clear glass in such projects as Ludwig Mies van der Rohe’s splendid Toronto Dominion Centre.

But the art of splintering light into the colours of the rainbow returned to architecture with Romanticism. That 19th-century movement in the arts saw the renewal of things the medieval glass-makers knew well: how to paint with light, how to shape and mould interior space with colour, how to fashion moods of devotion with symbols and images and abstract patterns.

Toronto artist Sarah Hall is today one of the world’s most talented inheritors of this venerable tradition. And with nearly a thousand works to her credit, she is also one of the most prolific living contributors to her art. Over a career spanning some 35 years, her highly expressive, richly colourful projects have been installed in churches, synagogues, schools and other public places, including an embassy in Ottawa and Toronto’s Scotia Plaza, across Canada and the United States.

A book that acknowledges Hall’s accomplishment has been overdue for some time, but at last it has arrived. It’s called The Glass Art of Sarah Hall and is published by Glasmalerei Peters, a German fabrication studio that has translated several of the artist’s complex designs into reality. This portfolio of 27 installations includes a brief introduction by architectural historian Karen Mulder and a thoughtful essay on glass, spirituality and Hall’s distinctive esthetic by J. S. Porter, a Hamilton, Ont., poet and essayist.

“The visual artist’s task is to renew — in a world of throwaway marketing images intended to seduce or numb — the viewer’s relationship with the ancient qualities of the heart by new pictorial means,” Porter writes. “Reconnecting with the sacred means revitalizing spiritual traditions that have borne transcendent light throughout human cultures for centuries.”

In Porter’s view — and he is certainly correct — Hall performs this task in an original and penetrating way. “Her windows,” he notes, “call us into reverence and contemplation; they evoke wonder and mystery.” They do so by presenting images deeply ingrained in the history of the Christian West — the Cross, the waters of Creation and baptismal Re-creation, the fire of the burning bush and Pentecost — in very fresh, vibrantly hued visual languages.

If Hall’s vocabulary of symbols and signs is usually traditional — whether the tradition she is working in is Christian or Jewish or other — her search for creative means equal to the job of communicating ancient meanings has taken her far afield from the realm of simply tinted glass. She casts prisms for inclusion in some works; she hand-paints, laminates, sandblasts and screen-prints her panes and fragments of glass. And in recent years, she has been especially interested in the possibilities for visual drama afforded by new glass products coming off the technological assembly line.

Hall first demonstrated the incorporation of photovoltaic cells in her glass art in 2005, for example, in a piece she contributed to Canada’s entry in the U.S. Department of Energy’s Solar Decathlon, an international competition of solar-powered house designs held each year in Washington. This beautiful secular work was called Northern Light, and its cells produced energy that was stored and later used to illuminate the building’s foyer.

Her most ambitious handling of new materials so far, however, and the first permanent installation of photovoltaic glass art in North America, is the award-winning True North/Lux Nova. Fabricated in Germany, this lyrical, devout composition, illustrated well in the book under review, was designed for the façade of a 12-metre ventilation tower over an underground theological library at Regent College, a Christian studies institution on the campus of the University of British Columbia in Vancouver. True North/Lux Nova stands in a park at Regent College’s heart, recalling Christian devotion with its inscription of the Lord’s Prayer in Aramaic, the language of Jesus.

The religious theme of the piece is further reinforced by 12 crosses that shimmer against a cascade of silvery blue, violet and white. And this luminous tower of fused and etched glass also provides a memorable reminder of the peace that can reign between humankind and the environment: It declines to add to the burden already on the public electricity grid, and, instead, creates from sunshine (via embedded solar cells) the energy needed to power a column of light that glows by night behind the glass panels.

Leafing through this volume, I found myself thinking back again and again to a line from Porter’s catalogue essay: “She makes visible the usually invisible thrust of life.” Sarah Hall does exactly that, celebrating in new glass the old symbols by which we know God, life and each other.
