The present article will reconsider the historiographical value played by the 182 bc Antigonid military ritual – known as Xanthika. Firstly, in order to appraise ancient historiographical adaptations and modern analytical shortcomings, this article will retrace extant ancient sources and, secondly, its current state-of-the-art. Thirdly, the original Polybian treatment will be discerned from its Livian adaptations, and historiographical distinctions will be proposed for each version. Fourthly, the Xanthika will be reconsidered as a key historiographical device through which Polybius coupled the Hellenic themes of Alexandrian legitimacy, deep-rooted tyrannical discord, and irreversible royal decadence within a larger narrative of the Roman ascendance towards world dominance.
