His terrors reach the direful king of Hell;
He fears his throws will to the day reveal
The realms of night, and fright his trembling ghosts.
This to prevent, he quits the Stygian coasts,
In his black carr, by sooty horses drawn,
Fair Sicily he seeks, and dreads the dawn.
Around her plains he casts his eager eyes,
And ev'ry mountain to the bottom tries.
But when, in all the careful search, he saw
No cause of fear, no ill-suspected flaw;
Secure from harm, and wand'ring on at will,
Venus beheld him from her flow'ry hill:
When strait the dame her little Cupid prest
With secret rapture to her snowy breast,
And in these words the flutt'ring boy addrest.
O thou, my arms, my glory, and my pow'r,
My son, whom men, and deathless Gods adore;
Bend thy sure bow, whose arrows never miss'd,
No longer let Hell's king thy sway resist;
Take him, while stragling from his dark abodes
He coasts the kingdoms of superior Gods.
If sovereign Jove, if Gods who rule the waves,
And Neptune, who rules them, have been thy slaves;
Shall Hell be free? The tyrant strike, my son,
Enlarge thy mother's empire, and thy own.
Let not our Heav'n be made the mock of Hell,
But Pluto to confess thy pow'r compel.
Our rule is slighted in our native skies,
See Pallas, see Diana too defies
Thy darts, which Ceres' daughter wou'd despise.
She too our empire treats with aukward scorn;
Such insolence no longer's to be born.
Revenge our slighted reign, and with thy dart
Transfix the virgin's to the uncle's heart.
She said; and from his quiver strait he drew
A dart that surely wou'd the business do.
She guides his hand, she makes her touch the test,
And of a thousand arrows chose the best:
No feather better pois'd, a sharper head
None had, and sooner none, and surer sped.
He bends his bow, he draws it to his ear,
Thro' Pluto's heart it drives, and fixes there.
-Ovid's Metamorphoses, translated by Samuel Garth
So in short, there were some volcanic quakes. Hades, fearing the land would split open and reveal the ghastly shade of the Underworld to the mortal one, went up to investigate. And Aphrodite angered with how Persephone (Proserpine) was staying a virgin like Athena and Artemis, convinced Eros (Cupid) to shoot Hades with an arrow so he would carry Persephone off
A large chunk of the Greeks myths are Zeus doing his thing, but I feel like people forget how... vital Aphrodite is to many Greek Myths too...
