Proserpina
Enna's flowers
Enna was the Sicilian meadow where Proserpina picked flowers before Pluto abducted her. The myth says she was gathering narcissus when the earth opened.
The binding fruit
Pomegranate seeds. Eating underworld food binds you there permanently—Proserpina ate six seeds, so she must spend six months per year in Hades.
Tartarean grey
Tartarus is the deepest pit of the underworld, below even Hades. The adjective makes the greyness specifically hellish, not just dim.
Third-person lament
She hears herself mourned in third person—'Proserpine' instead of 'me.' The distance between self and name mirrors her split existence.
