In this artwork, how is the Painting discussed?
Mnemosyne began as an oil study for Astarte Syriaca, for which Jane Morris sat over the winter of 1875–1876, but Rossetti later worked it up as an image of Mnemosyne, the Greek personification of Memory. Rossetti wrote to his mother about the two paintings on 29 April 1876:"I have twice commenced the Venus Astarte subject. The second commencement is I believe quite a success for me—my best; and the heads are now all fully secured. I have lately been working up as a separate picture the principal head of the first commencement, which, though I was bent on doing it still better for the picture, is by no means a failure. I am making it into another design of head and hands only, to be called Memory, or La Ricordanza which word I suppose (though it might be rather obsolete) is as admissible Italian as 'Rimembranza'." 
A month later Rossetti was considering ordering a frame for the painting and selling it to Clarence Fry. Fry declined and in July 1876 Leyland advanced Rossetti 300 pounds for the painting, although he was concerned that the painting was too large for his drawing room.  Rossetti did further work on the painting in 1879 and adjusted the frame in 1880, before delivering it to Leyland in 1881.  It was one of Rossetti's last completed canvases.Inscribed on the picture's frame is:Thou fill'st from the winged chalice of the soul 
Thy lamp, O Memory, fire-winged to its goal.
