Proserpina was the Roman name for the goddess whom the Greeks called Persephone — daughter of Ceres (Demeter), wife of Dis Pater (Hades), queen of the underworld for the half of the year when she was below, returning to her mother for the half when the earth was fertile. The Roman story followed the Greek closely, and indeed by the late Republic the cult was thoroughly Hellenized, with the Greek myth taught in Roman schools as the explanation of the seasons. But the cult was old in Italy too, and the Roman Proserpina retained some features of an earlier Italic underworld goddess.
She was worshipped together with Dis Pater at the underground altar in the Campus Martius (the Tarentum, mentioned in the entry on Dis Pater above), and the Ludi Saeculares were dedicated to the pair. Her separate cult — without Dis — was less developed in Rome itself than at the great south-Italian sanctuary at Locri, where the Greek cult of Persephone was practiced from the sixth century before our era and where Roman pilgrims of later generations would still come to make offerings. The famous pinakes of Locri — small terracotta plaques depicting Persephone with Hades, Persephone with Ceres, Persephone with Hermes — are now in the Reggio museum and are among the most precious documents of pre-Roman Italian religion.
Proserpina was also identified with the moon, particularly with the moon in its waning phase; this lunar identification was not Greek but Italic, an older stratum that survives in the philosophical handbooks. In the Roman imagination, she was the queen of the dead in winter, the bride of the spring at her return, and the moon between earth and heaven — a triple figure, more developed in Italy than her Greek prototype. The poets of the imperial period, especially Claudian (whose unfinished De Raptu Proserpinae of c. 400 CE is the great Latin treatment), gave her a richness of poetic detail equal to the Greek.
