Chapter 3 treats Herodotus’ use of the catalogue and the general problem of quantifying goods on a large cultural scale, as well as the specific use of the list as a cipher for imparting value. In the Histories, I argue, the genre of historiography and the nascent administrative inventory tradition coalesce. We find multiple examples of lists used to prove points and express value, and the characters and audience of the Histories, deeply invested in quantifying and displaying their wealth and possessions, use the list format to enact and prove their own worth. Meanwhile, Herodotus’ use of the term apodeixis for his work — also the technical word for an inscribed inventory — reveals that he conceives of his project as a grand multimedia catalogue of everything of importance to the Greek world. He has transferred the discrete uses of lists available to him to his own new type of text, thus incorporating old forms while distinguishing the Histories from previous genealogical works.
