A Dictionary of Greek and Roman biography and mythology

(Λύσανδρα), daughter of Ptolemy Soter and Eurydice, the daughter of Antipater. She was married first to Alexander, the son of Cassander, king of Macedonia, and after his death to Agathocles, the son of Lysimachus. (Dexippus, apud Syncell. p. 265; Euseb. Arm. p. 155; Paus. 1.9.6; Plut. Demsetr. 31.) By this second marriage (which took place, according to Pausanias, after the return of Lysimachus from his expedition against the Getae, B. C. 291) she had several children, with whom she fled to Asia after the murder of her husband, at the instigation of Arsinoe [AGATHOCLES], and besought assistance from Seleucus. The latter in consequence marched against Lysiimachus, who was defeated and slain in battle B. C. 281. From an expression of Pausanias, it appears that Lysandra must at this time have accompanied Seleucus, and was

possessed of much influence, but in the confusion that followed the death of Seleucus a few months after we hear no more either of her or her children. (Paus. 1.10.3_5.)
