Herodotus’ depiction of Miltiades’ transgression in the sanctuary of Demeter Thesmophoros on Paros is marked by the intriguing phrase κινήσοντά τι τῶν ἀκινήτων (6.134.2). We examine this proverbial phrase, whose implications for Herodotus’ portrayal of Miltiades’ downfall have not yet been fully acknowledged. The article draws attention to the widespread concept of sacred immovables (ἀκίνητα) that were protected by imprecations, and suggests that Miltiades triggered a contingent curse protecting divine property. Herodotus configures the episode of Miltiades on Paros as a narrative of entrapment and steers his readers to view Miltiades’ fate as the consequence of a curse at work.
