Just finished watching the final episode of the first series of Domina, a very smart new show from Sky, based on the life of Liva Drusilla - wife of Augustus Caesar. I really liked it, mainly because it continued the theme of complexity and double-dealing initiated in the character by Sian Phillips, who played Livia in the series I, Claudius. I saw that when it originally broadcast in 1976, and have seen it a couple of times since..
This version of her story presents a much younger version of Livia, but I found many similarities and links which enhanced both series. You do need to concentrate to keep up with her, but its a worthwhile effort . . . Give her a watch!
