Octavia and the Theatre of Marcellus

The portica also contains two libraries, so Greek and Latin library, which are dedicated to her son Marcellus after he dies. Also nearby Augustus was already building a theatre, but he calls that the theatre of Marcellus as well. This whole complex is about Octavia's family really. Some ancient authors said it was actually built by Augustus. But even if you believe that, it's clearly useful to attach her name to it, at the very, very least.
