Ocnus (Greek Ὄκνος, the procrastinator ) is a figure from Greek mythology.


Ocnus - son of the Tiber - was the husband of a licentious and profligate woman. As an old man Ocnus was among the damned in Hades. In Tartarus, he had forever a rope made of rushes, lichens, whose ready- end but was repeatedly eaten by a donkey. Ocnus to have been a hard-working man in life, his fortune was but by rapidly brought by his wife, which his situation in Tartarus resembles in life.

Weave the rope of Ocnus is an idiom for a tedious work that will never end. The phrase, however, was superseded by the Sisyphean task, the similar means and how the Tantalus Tartarus comes from.
