A page from the facsimile edition of Burne-Jones' Flower Book, one of 38 watercolour designs reproduced by Henri Piazza et Cie, for the Fine Art Society, London in 1905.

'Grave of the Sea' may refer to sand spurry (Spergularia marina), a plant commonly found throughout England in sandy waste places near the sea.

This image evokes three images Burne-Jones painted of a mermaid and a drowned man, entitled 'Depths of the Sea' (Ashmolean Museum, circa 1875; Private Collection, 1886; Fogg Art Museum, Harvard University, 1887).
