<P> The first four stanzas of the poem are inscribed on the frame of the painting . </P> <P> The blessed damozel leaned out From the gold bar of Heaven; Her eyes were deeper than the depth Of waters stilled at even; She had three lilies in her hand, And the stars in her hair were seven . </P> <P> Her robe, ungirt from clasp to hem, No wrought flowers did adorn, But a white rose of Mary's gift, For service meetly worn; Her hair that lay along her back Was yellow like ripe corn . </P> <P> Herseemed she scarce had been a day One of God's choristers; The wonder was not yet quite gone From that still look of hers; Albeit, to them she left, her day Had counted as ten years . </P>

What does the dove in the blessed damozel symbolize
