Atia of The Julii

Atia of the Julii is a fictional character from the HBO/BBC/RAI original television series Rome, played by Polly Walker. The niece of Julius Caesar and mother of Octavian/Augustus and Octavia, she is depicted as a cheerfully amoral and opportunistic manipulator. Her family connections and sexual liaisons have brought her into contact with some of the most powerful individuals in Rome, making her a highly influential figure in Roman society. Atia is very loosely based on the historical figure Atia Balba Caesonia about whom little detail is known. Rome Historical Consultant Jonathan Stamp identifies the historical figure Clodia as the primary basis for the character of Atia.

You are swearing now that some day you will destroy me. Remember: far better women than you have sworn to do the same. Go and look for them now.
— Atia, De Patre Vostro
