This study focuses on the imagery of youth and old age in the plays of Euripides, especially the Suppliant Women, considering frequently used words in each play according to a formula developed by Guiraud. The study identifies a motif, the rejuvenation theme, an elaborate interaction between young and old, in the Suppliant Women and in: Alcestis, Heraclidae, Andromache, Hecabe, and Heracles. The difference between the use of neos (young, new) in the Suppliant Women and in the other plays is statistically significant. This word helps Euripides contrast two different kinds of youth: the fearful, rash, and animalistic (Theban); and that which has been properly schooled and led (Athenian). The greatest ground in the Suppliant Women for praising Athens is in her treatment of the young as a politically valuable force.
