The picture takes its title from W E Henley's poem 'I M Margaritae
Sorori', no 35 in his Echoes, 1872-89:
Night with her train of stars
And her great gift of sleep.
It was given to Birmingham in 1915 by the E R Hughes Memorial Committee and is possibly the artist's masterpiece, although the blue tonality and soft sfumato, achieved by an elaborate process of stippling, are very characteristic.
