 Homer also confirmed Hypnos and Thanatos as twin brothers in his epic poem, the "Iliad", where they were charged by Zeus via Apollo with the swift delivery of the slain hero Sarpedon to his homeland of Lycia.Counted among Thanatos' siblings were other negative personifications such as Geras (Old Age), Oizys (Suffering), Moros (Doom), Apate (Deception), Momus (Blame), Eris (Strife), Nemesis (Retribution) and even the Acherousian/Stygian boatman Charon.Thanatos was loosely associated with the three Moirai (for Hesiod, also daughters of Night), particularly Atropos, who was a goddess of death in her own right.
