- But in fear of this, the almighty father hid them in black caves, and placed a mound and high mountains over them, and he gave them a king who, under a binding agreement, would know both to suppress them and to give them loose reins, when ordered.
- But, fearing this, the Sire omnipotent / hath buried them in caverns dark and deep, / and o'er them piled huge mountains in a heap, / and set withal a monarch, there to reign, / by compact taught at his command to keep / strict watch, and tighten or relax the rein.

Aussi, pour réprimer leur fougue vagabonde, / Jupiter leur creusa cette prison profonde, / entassa des rochers sur cet affreux séjour, / et leur donna pour maître un roi qui, tour à tour / irritant par son ordre ou calmant leurs haleines, / sût tantôt resserrer, tantôt lâcher les rênes.
