Focus on Lady Lilith and explain the Body's Beauty and Soul's Beauty.
Rossetti began painting Sibylla Palmifera before persuading George Rae to commission it in late 1865. The final price was 400 guineas.  He worked sporadically on the painting and only completed it in December 1870.  In June 1869 he received £200 from Leyland for a copy that was never completed.
The name Palmifera means "palm-bearer," and the model holds a palm in her hands. The palm, together with the inclusion of butterflies, may indicate the spiritual nature of the painting. This painting also has flower symbolism – using red roses and poppies in this case – and an unrealistic background space.Rossetti wrote the sonnet "Soul's Beauty" to accompany the painting Sibylla Palmifera, just as he wrote the sonnet "Lilith" to accompany the painting Lady Lilith.
Both pairs of poems and pictures were first published, side by side, in Algernon Charles Swinburne's Notes on the Royal Academy Exhibition in 1868.  In 1870 the poems were published again in Rossetti's Sonnets for Pictures.
It was not until 1881 however that the sonnets became a true pair.  At that time Rossetti decided to directly contrast the two poems, renamed "Lilith" to "Body's Beauty" and published them on consecutive pages of his book The House of Life as sonnets LXXVII and LXXVIII.
