After completing “First Man in Rome” Wednesday, we will be turning to Tacitus and to the barbarians.
Of Tacitus, we'll read The Agricola and The Germania, also available online: Agricola and Germania.
As to the “barbarians” – mostly in Northern Europe – we have The Barbarians Speak: How the Conquered Peoples Shaped Roman Europe, by Peter S. Wells.
The chat was originally scheduled for October 4 and 18, but this may not be enough, and we'll play it by ear, if necessary splitting the second Gibbon chat that follows.
Of neither book I could find an audio version. If someone knows of any, please respond in comments below.
