Perhaps this is the moment Iphigenia recognizes Orestes in Euripides' "Iphigenia in Aulis" The painting shows a pensive Orestes, his sister Iphigenia, his friend Pylades, King Thoas and a chorus of young and old women. Behind them is a statue of Diana with her quiver. Excavated in Resina in 1749. Copperplate engraved by Tommaso Piroli from his own "Antichita di Ercolano" (Antiquities of Herculaneum), Rome, 1789. Italian artist and engraver Piroli (1752-1824) published six volumes between 1789 and 1807 documenting the murals and bronzes found in Heraculaneum and Pompeii.
