The Fires of Pompeii (TV story)

"We're in Pompeii, and it's Volcano Day!"

- The Doctor

Synopsis
The Doctor and Donna travel to Pompeii, the night before Mount Vesuvius erupts. When they arrive in A.D. 79, they discover psychic powers and beasts of stone running riot in the streets of old Pompeii. The time-travellers face their greatest challenge yet – can established history be changed, or must the Doctor let everyone die?

Plot
The episode begins with the Doctor and Donna exiting the TARDIS in what the Doctor claims is Rome in the first century A.D.  Donna, noticing that the writing is in English, is sceptical--until the Doctor explains to her that the TARDIS's telepathic circuits are translating for her. However, he's not so sure it's Rome... and Donna points out there is only one hill and not Rome's famous seven... and that it is smoking. Thus - as an earth tremor rocks the streets - the Doctor realises they have arrived not in Rome, but in Pompeii, on 23rd August - the day before Vesuvius' eruption.

As they retreat to the TARDIS, Donna tries to convince the Doctor that he should help evacuate the city, but he tells her he cannot interfere in established events. On arriving where they left the TARDIS, they find that a nearby stallholder has sold it to local marble merchant Caecilius, as a piece of "modern art".

Meanwhile, a member of the Sibylline sisterhood reports back on the appearance of a mysterious blue box in the marketplace, which they find is a fulfillment of a Sibylline prophecy.

At Caecilius's house, his wife Metella is preparing their prophetically-gifted but sickly daughter Evelina for the arrival of the town's augur Lucius Petrus Dextrus. The Doctor and Donna arrive before him and, when Dextrus arrives, he and the Doctor have a cryptic conversation that confirms the Doctor's worst suspicions: an alien influence is afoot in Pompeii. Worse yet, Caecilius unveils a marble plaque he has produced to Dextrus' designs... and it is recognizably an electrical circuit. Intrigued, the time-travellers stay--but, after the Doctor accidentally insults Roman religion as "official superstition", Dextrus and Evelina "prophesise" truths about the Doctor and Donna, seeing their real names, naming Gallifrey and London as their true homes, mentioning the Doctor's presence at the Medusa Cascade, his status as a "Lord of Time", and Gallifrey's destruction. Evelina also states that his true name is not Doctor but is in fact "hidden" and that "she" is returning (possibly a reference to Rose Tyler), and Dextrus warns Donna that "there is something on your back".

When Dextrus has gone, Donna investigates Evelina's mysterious skin ailment--and finds that the young woman's skin is turning into stone. Meanwhile, the Doctor is shown a hypocaust system powered by hot springs from Vesuvius itself and from which come monstrous sounds from "the gods of the underworld". This system, he is told, was installed after the A.D. 62 earthquake, on instructions from Dextrus and the other soothsayers. From that time onwards, the soothsayers have been inhaling rock dust from these hypocausts and all their predictions have been uncannily accurate--though they have not predicted Vesuvius' imminent eruption.

The Doctor and Quintus break into Dextrus' house, finding a stone circuit board like those seen earlier in Caecilius' house. Meanwhile, Evelina gives Donna a stola, and talks about a teenager's life in Pompeii. Donna's hints about Vesuvius' impending eruption find no purchase with Evelina, and Donna realizes that none of the seers have foreseen it. She tells Evelina about the eruption, which Evelina telepathically passes onto the sisterhood. They and their High Priestess decide it is false prophecy, and that Donna must be killed.

Quintus and the Doctor, meanwhile, have been apprehended by Dextrus. The Doctor helps him assemble the marble plaques into a circuit board; and, when Dextrus then threatens to have his guards kill them, breaks off Dextrus's completely petrified right arm. He and Quintus then escape--but, hearing underground footsteps going towards Caecilius's house, return there to find that Dextrus has summonned a giant humanoid stone-and-magma creature from the hypocaust. The Doctor tells Donna to go and get water while he attempts to reason with the creature, but she has kidnapped by the sisterhood. It is Quintus who throws water on it, causing it to die and collapse.

The Doctor goes to rescue Donna, who is about to be murdered by the sisterhood. Conversing with their high priestess, he finds she has completely turned to stone. She reveals that she is being used as a host by one of the Pyroviles, aliens who crashed to Earth millenia before and were only re-awakened by the A.D. 62 earthquake. One of their adult forms is the creature they saw at Caecillus' villa. They are a psychic race, and have bonded psychically with some of the local humans. The Doctor is, however, unable to find how they are seeing the future with such accuracy.

Holding off the high priestess with a water pistol, Donna and the Doctor escape down the hypocaust. Dextrus and the high priestess both declare that their Pyrovile-induced prophecy of a Pompeiian empire must now advance. As they run, Donna attempts to convince the Doctor to stop Pompeii's eruption, but he again refuses, telling her that the eruption is a fixed point in history--which he can see, because of the Time Lord ability to see the past, present and all possible futures at once (something he classes as a "burden"). Dextrus and the cult of Vulcan take the circuit boards to the mountain and he summons forth the adult Pyrovile to hunt Donna and the Doctor down. Dextrus, Donna and the Doctor reach the centre of the mountain, and Dextrus informs him that the Pyroviles intend not to launch a rocket back home via the eruption (their home planet of Pyrovillia having been "taken"), but to remain on and conquer Earth.

The Doctor and Donna then lock themselves in part of the Pyrovillian ship they have found, where they find the Pyrovile are using Vesvuius's power to set up a fusion matrix to convert millions of humans into Pyroviles. The matrix will bleed off so much of Vesuvius' pent-up energy that there won't be enough to trigger the eruption--which is why the soothsayers have been unable to see it. The Doctor can switch off the Pyrovillian circuitry and thus save the world from conquest, but in so doing he will cause the eruption and the deaths of himself, Donna and 24,000 people. They choose the latter as the lesser of two evils. Vesuvius erupts, and people in Pompeii watch in terror as ash falls upon them. Meanwhile, the Pyrovillian escape pod harboring the Doctor and Donna is launched into the sky and lands some distance away, between Vesuvius and Pompeii. The two friends run for the safety of the TARDIS.

The Doctor ignores the Caecilius family's plea for help and de-materialises the TARDIS with himself and Donna on board--but Donna confronts him and urges him to go back and save the town. If not the town, as the Doctor insists, then just one family. The Doctor relents, and materialises the TARDIS inside the Caecilus home, to the astonished delight of the family, who are huddled in a corner awaiting death.

The Doctor, Donna, and the Caecilius family watch the eruption from the surrounding hills - the Doctor explains why Evelina's visions (caused by a rift in time, akin to the Cardiff Rift, as a result of the explosion) have now stopped and promises that Caecilius and Pompeii will be remembered. Caecilius, awed by the fury of Vesuvius, coins the word volcano. The Doctor and Donna leave, with him acknowledging that she was right in that "sometimes I need someone" to stop and humanise him.

Six months later--in early A.D. 80--the Caecilius family has resettled in Rome. Caecilius has re-established his business; Evelina is a healthy and happy teenager once again (and dating, to her father's consternation); Quintus has given up his dissolute ways to train as a doctor; and Donna and the Doctor are worshipped as the family's household gods, with the TARDIS as their temple.

Story notes

 * One of episode writer James Moran's favourite stories is City of Death, so there's a deliberate reference to that Caecilius buys the TARDIS, thinking it's a piece of modern art. In City of Death, the TARDIS is parked in an art gallery, causing a pair of critics (John Cleese and Eleanor Bron) to discuss its artistic merits.
 * The Pyrovile were originally called Pyrovillaxians. Then this was shortened to Pyrovellians. Then Pyrovile...
 * In the corresponding edition of Doctor Who Confidential (The Italian Job) Russell T. Davies states - or confirms, for those of us who suspected - that Caecilius and his family are based on characters from a series of Latin text books used in secondary schools.
 * Phil Cornwell (Stallholder) parodied the Ninth Doctor in a sketch for the Christmas 2005 edition of Dead Ringers (Christmas Day at Doctor Who's).
 * BBC4 broadcast three related programmes on the same evening as the original broadcast; "Earth: the Power of the Planet" (an episode about volcanoes) at 2010BST, "Pompeii: the Last Day" at 2110BST, and "10 Things You Didn't Know About Volcanoes" (actually broadcast at 0155BST the following morning). The Radio Times listing for The Fires of Pompeii made reference to "Pompeii: the Last Day".
 * The Fountain in this story is in fact the Cloning vat from The Sontaran Strategem.
 * When the water in the fountain shakes, it could be a reference to Jurassic Park, for the water always shook when danger was coming.
 * Lucius Petrus Dextrus's middle name, Petrus, is Latin for "stone".

Filming Locations

 * Rome's Cinecittà Studios. Discounting Doctor Who: The TV Movie (1996), which was filmed in Canada, and Daleks in Manhattan, which featured some second-unit photography in New York City but nothing involving the cast, this is the first regular-series episode to be filmed outside the UK since the three-part serial The Two Doctors (1985), which was filmed in Spain in 1984.

Discontinuity, Plot Holes, Errors

 * The Doctor does not seem to recall (or at least does not mention) the events of The Stone Rose. The events of Stone Rose could've been locked in the back of his mind or at least pretended not to and besides, these events occur after this episode in AD 128. Spin off novels are not always completely canonical, either, so it's highly possible that the writers paid no attention to those events.
 * Donna says that the Doctor saved her in 2008 when Partners in Crime was set in 2009. (Donna could likely be referencing the events of The Runaway Bride, which occurred in late 2007.
 * After the Doctor and Donna go into the TARDIS, their hair is full of dust and Donna is crying but when they go back, they are both immaculate. (There could have been more than enough time for them to have cleaned themselves before returning to just a few seconds after they left Caecilius' house.)
 * The Chameleon circuit, although broken, allows the TARDIS to remain hidden to the untrained eye--so how did Caecilius spot it to offer to buy it? It's a perception filter, that is it is visible, but you don't want to see it, whereas Caecilius wanted to see the modern art, so the perception filter didn't work. As for the others, once attention is drawn to it, it can easily be seen. Humans tend to overlook the TARDIS, which is a feature of the chemeleon circuit(Human Nature also seems to go a long way in causing locals to ignore the TARDIS.)Caecilius glanced at the TARDIS and formed a mistaken impression of what he was seeing, but he never discerned its true purpose and and continued to believe he was seeing a simple blue box.)
 * The Seventh Doctor and Melanie Bush go to Pompeii at the same time and also get involved in time changing decisions. It is impossible at some point they don't find each other. (BFA: The Fires of Vulcan. Definately not impossible. The Tenth Doctor might have been purposely avoiding The Seventh Doctor, as it's not advisable that they meet, as we've seen before. Also, Big Finish is not always seen as canon. Also, whilst Donna and the Doctor were at town, the Seventh Doctor and Mel must be near the volcano and at night, vice-versa.)

Continuity

 * The Doctor refers to having visited Rome a long time ago (DW: The Romans).
 * The Doctor says he was in Pompeii a long time ago (BFA: The Fires of Vulcan).
 * Dextrus says that Donna has something on her back, this will be picked up on in DW: Turn Left.
 * The Doctor's discussion of time and not interfering harkens back to DW: The Aztecs in which the issue of history and non-interference was covered.
 * Lucius states that "She is returning." This is a possible reference to Rose Tyler's return later in the series.
 * When the Doctor arranges the stone tablets into the correct order, they appear to show multiple circles linked by lines to a central core. This could be a reference to the 27 planets locked in the Medusa Cascade in The Stolen Earth and Journey's End.

DVD and other releases

 * It will be released on the Series 4 boxset DVD in November 2008.


 * It was released as part of Series 4 volume 1 on June 2nd 2008 along with 'Partners in Crime' and 'Planet of the Ood'.
