was the daughter of
Magas of Cyrene and became the wife of Demetrius, thus giving him the throne of
Cyrenaica. Not much is known about him until 249 BC. Greek Cyrenaean king
Magas of Cyrene died in 249 BC or 250 BC. His widow was the powerful Greek monarch
Apama II. She was Demetrius' niece through his paternal half sister
Stratonice of Syria and her husband
Antiochus I Soter of the
Seleucid Empire. Apama summoned Demetrius from Macedonia. She offered her daughter with Magas (her only child)
Berenice II in marriage to Demetrius. Demetrius in return would become King of
Cyrenaica and protect Cyrenaica from the
Ptolemaic dynasty. Demetrius agreed to Apama's request and married Berenice. When he married Berenice and became king, there was no opposition in his rise to the throne, but he became ambitious to the point of recklessness. Sometime after his marriage to Berenice, Demetrius and Apama became lovers. Jealous of her husband's affair with her mother, Berenice argued with both of them and consented to the assassination of Demetrius, who died in Apama's arms. The poem
Coma Berenices by Greek poet
Callimachus (lost, but known in a Latin translation or paraphrase by
Catullus), apparently refers to her coup against Demetrius: "Let me remind you how stout-hearted you were even as a young girl: have you forgotten the brave deed by which you gained a royal marriage?" ==First marriage and children==
