 As mentioned, Boethius finds the source of his conception of eternity in Plato. In the Timaeus (37E6–38A6) Plato contrasts the eternal forms with the time-bound created world, the world of change and becoming. Time was created along with the heaven (38B5)—meaning at least that time is the measure of change, and perhaps that it is identical with the movements of the heavenly bodies (a view later critiqued by Augustine (Confessions, Book XI. xxiii)). Plato’s idea of eternity in the Timaeus seems to be that of a timeless duration. The Forms endure in the temporal order in which “time is the moving image of eternity”. One can trace a similar idea of timeless eternity back to Parmenides (though exactly what he means is the subject of scholarly dispute).
