This paper reexamines the problem of the localization of one of the most significant episodes of the Arzawan campaigns of Muršili II, which took place around 1318–1317 bc and revolved around Mount Arinnanda and the city of Puranda. Instead of the traditional localization of Arinnanda and Puranda in the vicinity of Abaša/Ephesus, it is argued that the events are to be set in the Knidian peninsula (southwestern Caria). This is supported both by the localization in southern Caria of Attarimma, Ḫuršanašša and Šuruda, the three cities from which the refugees of the episode originate (Oreshko 2019), and by the identification of Puranda with Πύρινδος, a locality associated in sev- eral Greek inscriptions with Knidos
