Arsinoë ruled with her brother for approximately five years, until her death in 270 B.C. AS was customary in Macedonian courts, she inaugurated her reign by accusing all her rivals of treason and having them eliminated. She was the first Egyptian queen whose portrait was shown with her husband’s on coins, and Theocritus and Callimachus celebrated her in poetry. The period when Arsinoë joined her brother in the government was characterized by a dramatic improvement in the military and political affairs of Egypt; Arsinoë herself was responsible for the expansion of Egyptian sea power.8 Though some historians condemn her for unbridled ambition, most agree that she surpassed her brother in talent for governing Egypt.
