Tacitus, Annals 11.31.2

“Messalina meanwhile, more wildly profligate than ever, was celebrating in mid-autumn a representation of the vintage in her new home. The presses were being trodden; the vats were overflowing; women girt with skins were dancing, as Bacchanals dance in their worship or their frenzy. Messalina with flowing hair shook the thyrsus, and Silius at her side, crowned with ivy and wearing the buskin, moved his head to some lascivious chorus.” – Tacitus, Annals 11.31.2
