Perhaps the most intriguing feature of Euripides' Iphigenia at Aulis is the tendency of the characters to alter their attitudes towards the human sacrifice. Menelaus and Iphigenia (and even Achilles, it would appear) each undergo a single but remarkable change of mind, while Agamemnon displays so much confusion and uncertainty in adjusting his attitudes that it is not perfectly clear just how many times he actually changes his mind. These about-faces are not merely responses to changing circumstances or fresh information; rather they dramatize in an unusually arresting fashion a characteristically Euripidean psychology that emphasizes those forces or tendencies, both inside and outside the mind, that work to disrupt or even preclude the moral, intellectual or psychological integration of the character.
Now although this psychology typifies Euripidean drama in general in varying degrees, it would appear to take a more extreme form in the I.A. than in much earlier plays such as Medea or Hippolytus. We shall find it of some interest then, after examining closely the characterization and psychology of this late play, to hazard a number of necessarily brief comparisons with some earlier plays and also with Sophoclean drama.
