Camus, in The myth of Sisyphus, mentions that
"There was in Athens a temple dedicated to old age. Children were taken there." ("Il y avait à Athènes un temple consacré à la vieillesse. On y conduisait les enfants").
Indeed, Old Age is mentioned as a deity in Hesiod's Theogony. It is Geras, son of Nyx (Night).
But I would like to ask for help finding documentation that supports the existence of a temple dedicated to old age in Athens, as I haven't been able to do so in Wikipedia & other online sources.
