The patera (‘drinking-bowl’) of King Pterelas that Amphitruo brings back as a trophy of his victory over the Teleboeans plays a central role in Plautus' Amphitruo. Amphitruo and Sosia plan to show it off to Alcumena to impress her and to aggrandize their triumph, and this military bragging characterizes Amphitruo as a modified miles gloriosus (‘braggart soldier’). Jupiter steals it and, in disguise as Amphitruo, gives it to Alcumena, wooing her and further solidifying her belief that she has just spent the night with her husband. After Amphitruo accuses his wife of lying when she states that she has slept only with him and that he gave her the drinking-bowl, he commands Sosia to open their box containing it to prove otherwise; of course, it has vanished, and its disappearance leads to more confusion and accusations. The drinking-bowl thus also serves as a physical token that might establish a character's identity, just like the cistella (‘box’) of Plautus' Cistellaria or Rudens, but with the twist that Jupiter's manipulation of the token intensifies misunderstanding rather than dispels it, per the usual model of comic anagnorisis. In short, this prop contributes greatly to Amphitruo's characterization, narrative development, and metatheatrical play.
