The wearisome goddess Erida can best be understood by reading the opening lines of Book 11 of the Iliad. After Eos [Dawn] sheds her gentle light on mortals and Immortals alike, Zeus sends Erida to the encampment of the Achaeans. She stands on the centermost of the beached vessels and SCREAMS!!! The hearts of the soldiers are hardened as they awaken. They no longer remember their fathers or their wives and children. They rise from their beds with the hateful screams ringing in their ears and they long for the sweetness of battle. Only blood will dispel the sanguine thrust that Erida has evoked.
[from four different translations]
In the following excerpts, none of the translators use the name Erida ... Richmond Lattimore calls her Hate but the other three call her Strife, which might be confusing because the goddess Eris is often referred to as Strife as well as Discord.
