This gold coin of Ptolemy II makes dynastic claims. The obverse shows the heads of Ptolemy II and Arsinoe II, his sister and wife. The Greek inscription means 鈥渙f siblings.鈥 It was common in Egyptian history and mythology for kings to marry their sisters, including the divine siblings, Isis and Osiris. Therefore, Ptolemy鈥檚 marriage to Arsinoe legitimized him as an Egyptian ruler. The reverse of the coin portrays the heads of their parents, Ptolemy I and Berenice I, with the inscription 鈥渙f gods.鈥 Ptolemy II used the coin to claim the divinity of his parents, thus emphasizing the legitimacy of his own and his sister鈥檚 rule.
