Is Tartarus the Greek equivalent of hell?

[The Rookie]

Tartarus means the Underworld.
Its ruler was Hades, the brother of Zeus.

Tartarus is the Greek equivalent of Hell.
Its reputation as a dark, menacing place was probably derived from the myths of Persephone's abduction by Hades and Orpheus' search for Eurydice.

There were several regions of Tartarus :
Ashphodel Fields, where ordinary souls would twitter forever like birds and bats;
The Pool of Lethe, where souls could drink to wipe out all memory of their lives; and its opposite, the Pool of Memory;
The Punishment Fields to detain the evil souls;
The Orchard of Elysium for those who had been virtuous.

Many in those days believe that neither the Underworld nor its ruler was particularly evil in intent.
