Stern he retains: e’en [221]to immortal gods
A foe. The hollow-sounding palaces
Of Pluto strong the subterranean god,
[222]And stern Prosérpina, there full in front
Ascend: a grisly dog, implacable,
Holds watch before the gates: a stratagem
Is his, malicious: them who enter there,
With tail and bended ears he fawning soothes:
But suffers not that they with backward step
Repass: whoe’er would issue from the gates
