Brian Clarke's Portia’s Dream is a companion sculpture to Caesar Released from the Prison of Ambition.

As in Caesar Released from the Prison of Ambition, Clarke's title references the events in William Shakespeare's Julius Caesar. In this play, Caesar’s wife Calpurnia foresees her husband’s death in a dream and warns him not to go to the Senate. Portia's Dream refers to Brutus's wife, who famously begs her husband to confide in her and later commits suicide.
