 Varro's more complex theology groups her functionally with Tellus, Terra, Venus (and thus Victoria) and with Libera as a female aspect of Liber.No native Roman myths of Ceres are known.According to "interpretatio romana", by which Roman deities were identified with their Greek counterparts, she was an equivalent to Demeter, one of the Twelve Olympians of Greek religion and mythology; this made Ceres one of Rome's twelve Di Consentes, daughter of Saturn and Ops, sister of Jupiter, mother of Proserpina by Jupiter and sister of Juno, Vesta, Neptune and Dis.
