Pausanias Description of Greece 1.10.3

[3] Erotic-passion [ erōs] has a way of bringing many calamities [ sumphrorai] for humans. Lysimakhos, although by this time of mature age and considered happy [ eudaimōn] in respect of his children, and although Agathokles had children by Lysandra, nevertheless married Lysandra’s sister Arsinoe. This Arsinoe, fearing for her children, lest on the death of Lysimakhos they should fall into the hands of Agathokles, is said for this reason to have plotted against Agathokles. People have already written [ graphein] about how Arsinoe got into a state of erotic-passion [ erōs] for Agathokles, and, being unsuccessful, they say that she plotted against his life. They say also that Lysimakhos discovered later his wife’s machinations, but by now, toward the end, he had no resources left, having lost all who were near-and-dear [ philoi] to him.
