The same three words as before, but with their forms now indicating a different function. Before, using the nominative case, we just said "this IS an island/river/town." Now with the genitive we're saying "so-and-so is this master OF the island/river/town." * Note that there's no Latin word here for "of". That idea of "belonging" is all in the ending! Note also that our book doesn't introduce genitive forms for words of the "oppidum" type, but this is a convenient place for us to do so. The three men we've picked here to be "domini" are the poets Ovid, Horace and Virgil (of which the greatest is Ovid).
