Plautus
For example, in  Miles Gloriosus, the titular “braggart soldier” Pyrgopolynices only shows his vain and immodest side in the first act, while the parasite Artotrogus exaggerates Pyrgopolynices’ achievements. Artotrogus  creates more and more ludicrous claims that Pyrgopolynices agrees to without question. These two are perfect examples of the stock characters of the pompous soldier and the desperate parasite that appeared in Plautine comedies.
