Aurora lies naked in the lower right corner, covered with carefully draped ropes of pink roses.
Set in opposition to Aurora, in the lower left corner is a dark-robed Night, who swirls away a black cloak.
[1] The flowers strewn around Aurora and the pale glow of her naked body are set in opposition to the shadowy drapery of Night.
According to art historian Elise Lawton Smith, Aurora's "lethargic pose ... may signify her transitional state between night/matter and light/spirit.
Thus her power (or triumph, as suggested by the title) derives not from her mythological status, but from her role as a spiritualist metaphor.
