"Among those was I who are in suspense"

(Canto 2, line 52)

The souls "in suspense" are the dwellers of the first circle of Hell, "Limbo". Among them are virtuous people from the time before Christ (like Virgil) and children who died before baptism; because they are without sin, they do not have to be punished in Hell, but because they never believed in Christ and were not baptized, they can neither ascend to Paradise and are left "in suspense". The latin world "limbus" means edge or boundary.
