During the contest of Achilles and Hector in the "Iliad, Zeus, weary from the battle, hung up his golden scales and in them set twin "Keres, "two fateful portions of death"; this, then, is known as the kerostasia. "Plutarch reports that "Aeschylus wrote a play with the title Psychostasia, in which the combatants were "Achilles and "Memnon. This tradition was maintained among the vase painters. An early representation is found on a black-figure "lekythos in the "British Museum; she observes "The Keres or φυχαί are represented as miniature men; it is the lives rather than the fates that are weighed. So the notion shifts." In a psychostasia on an Athenian red-figure vase of about 460 BCE at the "Louvre, the fates of Achilles and Memnon are in the balance held by "Hermes.  Among later Greek writers the psychostasia was the prerogative of "Minos, judge of the newly deceased in "Hades.
In "Egyptian mythology, where "Duat is the "Underworld, there would take place the "Weighing of the Heart, in which the dead were judged by "Anubis, using a feather, representing "Ma'at, the goddess of truth and justice responsible for maintaining order in the universe. The heart was the seat of the life-spirit ("ka). Hearts heavier or lighter than the feather of Ma'at were rejected and eaten by "Ammit, the Devourer of Souls.
For Christians, among the terrors that await at the "Last Judgment is the weighing of souls.["citation needed] "Sin is heavy, and sinful souls are to be consigned forever to "Hell. The courtly angelic knight in the central panel of "Hans Memling's "The Last Judgment, ca 1470 (National Museum "Gdańsk), is the "Archangel Michael, who separates the Just from the Damned in his "steelyard balance. Memling has treated a medieval genre of fresco, called in English examples a ""Doom" which kept the future terrors before the eyes of the faithful.
