At the start of this act, time is moving backwards: Orpheus travels back out of and into the Underworld, and Euridice dies once more. Then time moves forwards as Orpheus leaves the Underworld again.

Hades then a subscript marking (), and finally omitted entirely (). Perhaps from fear of pronouncing his name, around the 5th century BC, the Greeks started referring to Hades as Plouton ( "Ploútōn"), with a root meaning "wealthy", considering that from the abode below (i.e., the soil) come riches (e.g., fertile crops, metals and so on). Plouton became the Roman god who both rules the underworld and distributed riches from below. This deity was a mixture of the Greek god Hades and the Eleusinian icon Ploutos, and from this he also received a priestess, which was not previously practiced in Greece.
