In the second stanza of his poem Vlyublyonnost' (“Being in Love”) composed on the night of July 20, 1922, Vadim Vadimovich (the narrator and main character in VN’s novel Look at the Harlequins!, 1974) mentions luch (a moonbeam):
Pokuda snitsya, snis', vlyublyonnost',
No probuzhdeniem ne much',
I luchshe nedogovoryonnost'
