Damnatio Memoriae

14 AD. Agrippa Postumus, grandson of the recently-deceased Augustus, tries to avoid death at the hands of the next emperor, Tiberius. At his disposal: a couple of old manuscripts, a lamp, and a recalcitrant slave. And a powerful knowledge of the Art of Venus Genetrix, of course -- the magic eventually known as the Lavori d'Aracne.
