Persephone
Venus sends Cupid's sharpest arrow into the ruler of the underworld.
Ovid dedicates this next story to Ceres, goddess of grain, sister-consort of Jupiter, who "first broke the glebe with her crooked plow, giving birth to all the fruits of the earth."
Ceres is the mother of Proserpine by Zeus. You might know mother and daughter by their Greek names, Demeter and Persephone.
This is a story of the seasons. It begins with Typhoeus, serpent-giant of wind and fire, who had once challenged Zeus and lost. He now lies buried beneath Sicily.
Ovid
Typhoeus lies pinned beneath Sicilia: Pachynus grips his right hand, Lilybaeus his legs, Aetna weighs his head; spewing sand and flames, his struggles shake the lands.
Pluto, the king of silent shades, trembles lest yawning fissures might admit daylight into the underworld and terrify its ghosts.
Fearing such ruin, the dark despot rode forth in his soot-black car to survey Sicilia's foundations.
Having explored and proven no part was shattered, he laid aside his careful fears and wandered at ease through those parts, satisfied the island stood secure above Typhoeus and his restless force.
Venus Erycina beheld Pluto from her mount, resolving to extend Love's sway even into Tartarus, the third of realms allotted when the universe was portioned. She then embraced her winged son, Cupid.
Aphrodite (venus)
O Cupid, my son and strength, take up the arms by which you conquer all; aim your keenest arrow at him whom Fortune made last heir when the triple realm was cast by lot.
You master Heaven and the deep, bending Jupiter and every Sea-God; why should Tartarus escape our rule, when enlarging your mother's empire and your own is needful to our honor?
See how Pallas and javelin-hurling Diana disdain my power; so will Ceres' daughter choose virginity if we permit it. Unite this goddess, Proserpine, in marriage to her uncle.
Ovid
Cupid opened his quiver, chose—with his mother's aid—the keenest, surest shaft, braced knee against the pliant bow, and let it fly; the arrow flashed through air and struck Pluto in the breast.
