Composer Peter Schindler on this separate edition from Perpetuum mobile:

Summer is over, the fields have faded and withered. The fall harvest has been brought in and winter is approaching relentlessly. Once again the cold is upon us. The warm days will disappear into distant exile. “In exilium” (text no. 69 of the Codex Buranus) poetically lists all these classic features of the arrival of winter. This text also has an eternal truth – Veritas aeterna – at the ready as a sort of consolation: the power of the cold cannot weaken love! Thus we are reminded of those beautiful days. The summer is bid a peaceful farewell, trusting that spring and summer will return again next year and that rivers and streams will be freed from the ice.This movement at the beginning of Act 4 of „Perpetuum mobile“ begins with a broadly swinging melody reminiscent of the chants of monks from the ages of Notre Dame. The choral song proceeds plaintively at a calm tempo.
