This article argues that the game presented in the third scene of the third act of Plautus’ Asinaria involves a horseplay rather than an assplay (Asin. 697–710). This is suggested by the young master's name, Argyrippus, and by a list of equine terms occurring in the text: uehere, inscendere, descendere, subdomari, tolutim, quadrupedo, aduorsom cliuom, in procliui.
