The second episode of Doctor's Who's revived fourth series had the Tenth Doctor and Donna Noble enjoying a trip to scenic Pompeii. On the day that Mount Vesuvius erupted. The episode is generally remembered for the first appearance of Peter Capaldi and Karen Gillen, who would go on to play the Twelfth Doctor and Amy Pond, respectively. As far as historical episodes go, this was fairly accurate. Ok, the market scenes include a sign reading "Two amphoras for the price of one" when the plural of "amphora" is "amphorae." The statement that the Romans had no word for "volcano" before the eruption is also shaky at best. But other than that, they got most of the details accurate. Until Donna decided to wear something historically accurate, that is. At Donnas request Evelina and her mother give her a purple dress which she wears for the rest of the episode. For the most part, the dress is historically accurate, and fits in with what the rest of the cast are wearing. However, purple, an extremely rare and expensive colour of dye, was reserved for exclusive use by the upper tiers of society. Unless you were the Emperor, a member of his family, or an extremely high-ranking official or priest, you wouldn't even be able to buy the dye, let alone wear purple clothes. The colour remained restricted for centuries to come, and to this day is associated with royalty
With a (nearly) useless degree in English literature and a personal trainer qualification he's never used, Freddie spends his times writing things that he hopes will somehow pay the rent. He's also a former professional singer, and plays the saxophone and ukulele. He's not really used to talking about himself in the third person, and would like to stop now, thanks.
