3. Daughter of Ptolemy III. Euergetes, sister and wife of Ptolemy IV.

Philopator. She seems to be erroneously called Eurydice by Justin (xxx. 2), and Cleopatra by Livy (xxvii. 4). Her presence greatly encouraged the troops at the battle of Raphia (217), in which Antiochus the Great was defeated. Her husband put her to death to please his mistress Agathocleia, a Samian dancer (between 210 and 205). She was worshipped as [Greek: Thea Philopator]; she and her husband as [Greek: Theoi Philopatores] (Polybius v. 83, 84, xv. 25-33).
