ABSTRACT

Both the genitive and dative cases are used to show possession:

Ascanius lacrimās amīcī videt [genitive]

Ascanius sees the tears of a friend

populō Rōmānō numquam scrīptōrum cōpia fuit [dative]

there never was an abundance of writers for the Roman people (the Roman people never had …) [4.8] 1
