Recently I encountered a passage from a book The Mask of Socrates by Paul Zanker
There were passionately cultivated Romans who sought in such statues conversation partners, who used them, as Seneca says, as incitamenta animi (Ep. 64.9–10).
The passage from Seneca Ep. containing the phrase incitamenta animi does not strictly mention any "conversation" with the statues, but just mentions they can be used for incitamenta animi:
Why should I not keep statues of great men to kindle my enthusiasm, and celebrate their birthdays? (translation: Richard Mott Gummere)
probably I read too literally that passage? Or there was a practice of actually speaking to statues by some in Ancient Rome? But if not, how exactly those use the statues for inspiration or to "kindle their enthusiasm"? was that in a general sense like images or nice view -- or they used to have more "intimate" connection with them?
