For double SATB choir unaccompanied John Rutter wrote this anthem for the dedication of the Herbert Howells memorial window in Gloucester Cathedral in 1992. The first section is full of mystical intensity, and, with its iridescent chromatic harmonies is reminiscent of Howells's own music. After a more lively central section, the finale is ingeniously written and incorporates both the chorale melody and the opening motif.
