Arsinoe II

Arsinoë II was Queen consort of Thrace, Anatolia, and Macedonia by her first and second marriage, to king Lysimachus and king Ptolemy Keraunos respectively, and then Queen of the Ptolemaic Kingdom of Egypt by marriage to her brother, Pharaoh Ptolemy II Philadelphus. As an Egyptian queen she acquired the royal name Arsinoe Philadelphos, as well the title nswt-bjtj that may suggest she was co-ruler with her husband; the exact meaning of this elevation and whether it occurred during her life or posthumously is uncertain. After her death, Arsinoe was deified at the orders of her husband and the cult of Arsinoe Philadelphos became widespread in the Ptolemaic territories.
