I heard from my brother that the series features a homosexual relationship between Julius Caesar and Octavian. Not sure how he knew that, but it immediately turned me off from any interest I may have had in it.
Eeeewwww, so much for historical accuracy. Why do the people in Hollywood/TV have to make every Historical hero gay!
It would be easier for such a series to portray the ancient Romans and Greeks who weren't swallowing the sword (as it were).
That is not what happens on the show. What happens is that Caesar suffers an epileptic seizure, and is rushed into a secluded room so that noone will see his affliction. Octavius helps Caesar's personal assistant slave carry him into the room. While in the room, Caesar makes certain noises as he bites down on a scroll that is mistaken by a nearby cook for sexual gratification. When the seizure passes, Caesar and Octavius exit the room, unaware that the cook sees them leave. This then starts a rumor that the two were...well you know.
The show has portrayed Octavius as uninterested in sex so far, and his mother is concerned that he is too effeminate, but I doubt that the writers will take it any further because the historical Octavian is thought to have been exclusively heterosexual. He was married twice, and was said to have had many, many extramarital affairs with women.
Caesar too, so far, has been portrayed as only interested in women. Hopefully the writers and producers will keep to what is known with regards to the sex life of the main characters, as with Caesar, Antony, and Octavian, that means sex with women.
