I've loved this name ever since I read the novel "Bring Down the Sun" by Judith Tarr. Polyxena always brings to mind a head-strong, powerful young woman.
According to greek-names.info, Polikseni (po-lee-KSE-nee) is the modern Greek form of Polyxene and means "much hospitality" from the elements poly and xenia (hospitality). Despite being a compound word (two ancient Greek words put together), the name became popular towards the end of the first century BC. This is the name of a 1st-century (AD) Greek Orthodox saint whose name day is celebrated on 23 September. Polina, Kseni and Ksenia are diminutives of Polikseni.
