this passion. In Plautus these men are Demaenetus (Asinaria), Philoxenus and Nicobulus (Bacchides), Demipho (Cistellaria), Lysidamus (Casina), Demipho (Mercator), and Antipho (Stichus). Periplectomenos (Miles Gloriosus) and Daemones (Rudens) are regarded as senes lepidi because they usually keep their feelings within a respectable limit. All of these characters have the same goal, to be with a younger woman, but all go about it in different ways, as Plautus could not be too redundant with his characters despite their already obvious similarities. What they have in common is the ridicule with which their attempts are viewed, the imagery that suggests that they are motivated largely by animal passion, the childish behavior, and the reversion to the love-language of their youth. Female characters In examining the female role designations of Plautus's plays, Z.M. Packman found that they are not as stable as their male counterparts: a senex will usually remain a senex for the duration of the play but designations like matrona, mulier, or uxor at times seem interchangeable. Most free adult women, married or widowed, appear in scene headings as mulier, simply translated as "woman". But in Plautus' Stichus the two young women are referred to as sorores, later mulieres, and then matronae, all of which have different meanings and connotations. Although there are these discrepancies, Packman tries to give a pattern to the female role designations of Plautus. Mulier is typically given to a woman of citizen class and of marriageable age or who has already been married. Unmarried citizen-class girls, regardless of sexual experience, were designated virgo. Ancilla was the term used for female household slaves, with Anus reserved for the elderly household slaves. A young woman who is unwed due to social status is usually referred to as meretrix or "courtesan". A lena, or adoptive mother, may be a woman who owns these girls. Unnamed characters Like Packman, George Duckworth uses the scene headings in the manuscripts to support his theory about unnamed Plautine characters. There are approximately 220 characters in the 20 plays of Plautus. Thirty are unnamed in both the scene headings and the text and there are about nine characters who are named in the ancient text but not in any modern one. This means that about 18% of the total number of characters in Plautus are nameless. Most of the very important characters have names while most of the unnamed characters are of less importance.
