His concept of allochrony - initially introduced shyly as 'untimeliness', then later radicalized to an exit from modernity - is based on the idea, as suggestive as it is fantastic, that antiquity has no need of repetitions enacted in subsequent periods, because it 'essentially' returns constantly on its own strength. In other words, antiquity - or the ancient - is not an overcome phase of cultural development that is only represented in the collective memory and can be summoned by the wilfulness of education. It is rather a kind of constant present - a depth time, a nature time, a time of being - that continues underneath the theatre of memory and innovation that occupies cultural time.
