Do you mean “Λοιμός”?
Loimos does refer to a plague but Loigos means something more akin to… the aftermath of a plague, the deaths and ruin that occur because of it. Of course, that’s only a very specialized definition, and it can be used in a variety of situations, but in comparison to loimos, that’s a good way to distinguish them.
Temple of Portunus (Fortuna Virilis)
Goblet Inscribed with the Names of King Akhenaten and Queen Nefertiti
18th Dynasty, New Kingdom
This graceful, translucent drinking cup in the form of a white lotus blossom is treasured both for its beauty and its historical interest. The nomen (personal name) and prenomen (throne name) of Amenhotep IV are inscribed in the small panel on the side, between two cartouches surrounding the early titulary of the Aten (left) and a cartouche naming the principal queen, Nefertiti (right). Thus, the vessel must have been made before Year 5 of the king’s reign, when he changed his name to Akhenaten.
