Kerberos is first named in Hes., Th. 311, and he is the same hound of Hades which Homer knows and leaves unnamed… he admits everyone, fawning about them and wagging his tail: but anyone who tries to slip out of Hades again he devours.
Rohde establishes the philological origin of Kerberos in Hesiod and argues that the dog's primary archaic function was not to terrorize entrants but to prevent exit — fear of entry being a later, secondary elaboration.

Everyone was familiar with the guardian of the gate of Plouton, the malignant hound of Hades who admits everyone but lets no one out again. He is the same creature, long known from the adventure of Herakles, which is already named Kerberos by Hesiod.
Rohde frames Kerberos as the universally recognized gatekeeper of the dead whose functional definition — admission without release — is inseparable from the Heraklean labor tradition.

Herakles's journey was undertaken with the purpose of bringing back Kerberos, that furious hound of Hades of which I have already spoken.
Kerényi positions Kerberos as the singular object of Herakles' Underworld descent, the retrieval of the hound serving as the defining goal that structures heroic katabasis mythology.
Here, behind the temple of Chthonia lay a sacred precinct of Plouton or Klymenos with a chasm in the ground through which Herakles had once brought up Kerberos to the earth.
Rohde documents a cult site at Hermione where an actual topographic chasm was identified as the passage through which Herakles extracted Kerberos, illustrating how Underworld mythology was anchored to sacred local geography.

Kerberos is brought up from below at Hermione: Eur., HF. 615.
Rohde cites Euripides to corroborate the geographical and cultic localization of Kerberos's retrieval at Hermione, linking dramatic and topographical traditions.

Honey-cakes offered to the under-world, i,.13; v, 98; vii, 6.
Rohde's index notes the apotropaic honey-cakes given to pacify Kerberos among general funerary and Underworld offerings, cataloguing a minor but recurring ritual element.
