Prexaspes ( Greek: Πρηξάσπης, romanized: Prēxáspēs) was a prominent Persian during the reign of Cambyses II ( r. 530–522 BC), the second King of Kings of the Achaemenid Persian Empire. [1] According to Herodotus, when Cambyses ordered his trusted counselor Prexaspes to kill Bardiya (also known as Smerdis), the King's own brother, Prexaspes loyally carried out his order. [1] [2] Herodotus provides two versions of the murder. [2] After moving from Egypt (where he was stationed) to Susa, Prexaspes either killed Bardiya in a hunting field near Susa, or drowned him in the Erythrean Sea. [2]
After Cambyses' death, Prexaspes denied murdering Bardiya at first, but ultimately, in the words of Brill's New Pauly, "revealed before the assembled Persians the usurpation by the Magi ( Patizeithes), called for their overthrow and committed suicide (Hdt. 3,66 ff.; 74 ff.)." [1]
