I was in fact talking chiasmus and not intercalation. The NT is full of chiasmus too. Perhaps someone else can do better.
Chiasmus is rather typical of Greek and Latin formal poetry as well as prose.
First one woman is named, then a second woman is named, then a descriptive phrase concerning the second woman is given and lastly a descriptive phrase of the first woman is given. Of the three individuals named as victims of Claudius' purges, the last in sequence is described first, as we can tell by the feminine ending, then the second one named is characterized and finally Crassus comes in both first and last. Answering will strengthen your case. That is one of the reasons the two-women solution seems more likely. She's Mary the anointer of Jesus' feet.
