Here's something from moviepilot.com by Jancy Richardson about a "Controversial Incest Scene"...
Over at techtimes.com there was something by Cameron Koch called "7 Ways 'Game Of Thrones' Is Inspired By Historical Events."
Both assault and sex (which is consensual) between close relatives have always been in our stories because they've always been a part of life. We need more depictions in our modern media so that we can fight abuse and support love. Abuse should be shown for what it is; victims should be empowered, not made to feel alone and at fault. Loving or recreational encounters should also not be kept from our stories, and should be distinguished from abuse.
Targaryen Incest Isn't So Different From The Ptolemaic Dynasty in Egypt
The last dynasty to rule Egypt before the Roman conquest, Ptolemaic brothers and sisters often married one another. They also liked to use the same names over and over again. Every king during this nearly 275-year time period adopted the name Ptolemy, in honor of the original Ptolemy, who was appointed ruler of Egypt by Alexander the Great. Many of Ptolemy's queens (and often Ptolemy's sisters) were either named Cleopatra, Berenice or Arsinoe. It's a similarity shared by many of the Targaryen king's, who are often named Aegon in honor of the first Targaryen to conquer Westeros.
