Eruption of Souffrier

 was a painting by Turner which the Rani once had replicated on a room-divider screen protecting her TARDIS. As the name suggested, it was a portrait of a volcano erupting. Were an unauthorised person to approach, mustard gas would spew out of the top of the painted volcano. The Sixth Doctor thought it an odd choice for the Rani, because it was "too passionate for the Rani's sterile tastes". (DW: The Mark of the Rani; DWN: ''The Mark of the Rani)

Behind the scenes
The painting is never named in the serial, but the novelisation claims: "the room-divider screen . . . Painted in the style of Turner's, it portrayed, in sultry ambers and vivid scarlets, a smouldering volcano"

- Pip and Jane Baker The difficulty is that neither that description nor the image which shows up in the serial is reminiscent of . That painting is much darker, and notably bereft of "sultry ambers and vivid scarlet". The divider is actually painted in the style of Turner's other notable volcanic work, Eruption of Vesuvius.

If the Bakers are to be believed, and it is of the Souffrier explosion, then the full name of the painting in the real world is, The Eruption of the Souffrier Mountains in the Island of St. Vincent, at Midnight, on the 30th April 1812, from a Sketch Taken at the Time by Hugh P. Keane, Esquire.
