Ponos /ˈpoʊˌnɒs/ or Ponus /ˈpoʊnəs/ (Ancient Greek: Πόνος Pónos) is the personification of hardship or toil. According to Hesiod's Theogony, "painful" Ponos was the child of Eris (Strife), with no father.^[1] Compare with Cicero who has the similar Roman god Labor (Toil) as the son of the Nox (Night) and Erebus (Darkness).^[2]
