'The Death of Lady Macbeth' by Dante Gabriel Rossetti [sic]
From an article "Pictorial Types of Female Beauty in the Nineteenth Century" in Burr McIntosh Magazine, February 1909. An example of how you shouldn't always believe what you read because the picture's caption is wrong:) It is Beatrice who lies dying, not Lady Macbeth...
"Rossetti had a life-long interest in the Italian poet Dante. This painting shows an episode from the 'Vita Nuova'. In it Dante dreams that he is led by Love to the death-bed of Beatrice Portinari, the object of his unrequited passion.
This is Rossetti's largest ever painting.
