<P> In the Iliad, Achilles likens their relationship to that of man and wife (he often refers to her as his bride or wife) and compares it explicitly to the relationship between Menelaus and Helen, which was, after all, what the war is about . If the war was being fought because Helen had been separated from Menelaus, then what should the repercussions be for separating Briseis from him, is the question often agitated in his discourse . Briseis was said to have regarded Achilles as her husband as well . </P> <P> Achilles was angry at Agamemnon, and seethed with rage in his tent: made furious by the thought of Agamemnon sleeping with Briseis . When Achilles returned to the fighting to avenge Patroclus' death and Agamemnon returned Briseis to him, Agamemnon swore to Achilles that he and Briseis never shared a bed . </P> <P> Briseis was among those to lament and mourn over the death of Patroclus . She remained with Achilles until his death, which plunged her into great grief . She soon took it upon herself to prepare Achilles for the afterlife . According to some, following his death, Briseis: "...was given to one of Achilles' comrades - at - arms just as his armor had been", after the fall of Troy . </P> <P> In medieval romances, starting with the Roman de Troie, Briseis becomes Briseida and is the daughter of Calchas . She loves and is loved by Troilus and then Diomedes . She is later confused with Chryseis and it is under variations of that name that the character is developed further, becoming Shakespeare's Cressida . </P>
