In 1997, Brian Clarke designed the window above the Torah shrine for the new Chicago Sinai Congregation Synagogue. After a long period of moving to different locations since its establishment in 1861, the Sinai Congregation’s new building was designed by architect Dirk Lohan.

In Brian Clarke–Linda McCartney: Collaborations, published in 1997, Stefan Trümpler writes:

‘This window marks a phase in Clarke’s work where his interest in the grid, for a long time the token of a pictorial order reminiscent of early modernism, shifts and opens to an exploration of abstraction of an even more vibrant structure.’
