Cleopatra

Cleopatra VII was the last Pharaoh of Egypt and the wife of Mark Antony. (PROSE: State of Change, The Last Pharaoh) She was Greek, although it was a common mistake to think she was Egyptian. (PROSE: The Lonely Computer)

History
Cleopatra had a brother and a sister, Arsinoe. She married her brother, but later convinced Julius Caesar to have him murdered. She then took Caesar as a lover and had a son with him. After Caesar's death, Cleopatra took Mark Antony as a lover and convinced him to have Arsinoe murdered. Eventually she married Mark Antony and together they had three children, including at least one daughter. (PROSE: The Last Pharaoh)

The Sixth Doctor and Peri Brown watched Cleopatra's barge on the River Nile in preparation for the Battle of Actium. (PROSE: State of Change)

Behind the scenes

 * According to The Brilliant Book 2012, a book that contains non-narrative based information, the alternate Cleopatra was on Facebook. She was friends with River, Churchill and Napoleon Bonaparte. She was a fan of Vincent van Gogh and Silurian medicine and played live chess with Joseph Stalin; she also read the book Murder on the Sky Orient Express and joined the online groups Can I get 6,000,000,000 people to join this group before 5.03pm??? and I'm not being funny but I think this is all the Doctor's fault!
 * She was portrayed by Claire Bloom in the 1956 version of Caesar and Cleopatra.
 * The depiction of Cleopatra in The Lonely Computer is based on 's portrayal of the character in.
 * With the depiction of Cleopatra in The Last Pharaoh, Iain McLaughlin said this: "We (Iain and Claire Bartlett) did a bucketload of research into Cleopatra before writing The Last Pharaoh, reading up on the descriptions of her and checking out the coins with her face on from when she had moved into middle age. She had a big nose and a turkey neck. Nothing wrong with that, either. She was noted as being ordinary to look at but extraordinary to talk with. Intelligent, witty and charming. When I sent out the brief for that cover to Paul, I asked for the real take on Cleopatra rather than Liz Taylor (or even Amanda Barrie, who was, of course the definitive Cleo).
