I think most historians agree that the "she was much older" then him thing was part of his trying to find reasonable excuses to get rid of her. I think the Portuguese article must be wrong cause nearly everyone agrees 70/68 BC. Since she was giving birth to live children between 48/38 BC, she was probably no more then thirty when she married Octavian--so she was older, just not as old as people think. Also, considering she outlived Octavian and all her children, she couldn't have been too old at the time. Most of the stuff about Scribonia I think can't be fully trusted when you compare what Octavian said about her as opposed to what she actually did in her actions.

Anyway, I am looking forwards to seeing the new series when it finally comes--about Gaia, it actually looks as if she's going to be Vorenus' new girl.
