2. Known also by the name of Stateira, was the elder daughter of Dareius III., and became the bride of Alexander at Susa, B. C. 324. Within a year after Alexander's death she was treacherously murdered by Roxana, acting in concert with the regent Perdiccas, through fear of Barsine's giving birth to a son whose claims might interfere with those of her own. (Plut. Alex. 70, 77; Arr. Anab. vii. p. 148d.; Diod. 17.107.) Justin (11.10) seems to confound this Barsine with the one mentioned above.
