 Crises in the Rimsky-Korsakov household may have been a factor—the serious illnesses of his wife and one of his sons from diphtheria in 1890, the deaths of his mother and youngest child, as well as the onset of the prolonged, ultimately fatal illness of his second youngest child.He resigned from the Russian Symphony Concerts and the Court Chapel and considered giving up composition permanently.After making third versions of the musical tableau "Sadko" and the opera "The Maid of Pskov", he closed his musical account with the past; he had left none of his major works before "May Night" in their original form.
