Down to her inmost centre deep has shook;
Then, rending with a yawn, at once made way,
To join the upper and the nether day:
While wondering eyes, the dreadful cleft between,
Another starry firmament have seen.
Each deadly kind, by nature formed to kill,
Fears the dire hags, and executes their will:
Lions to them their nobler rage submit,
And fawning tigers crouch beneath their feet:
For them the snake foregoes her wintry hold,
