Abstract
Thirteenth-century debates on time are frequently reduced to the opposition between an Ancient tradition, embodied by Augustine, and the Aristotelian philosophy as “physicalist” reading of the problem. However, before the diffusion of the Latin translation of Aristotle’s Physics, notions such as ‘time’, ‘eternity’, ‘aevum’, and ‘present’ have a rich range of meanings and nuances which cannot be considered a mere repetition of an ‘Augustinian model’. A systematic analysis of selected passages of Marius Victorinus’ Explanationes in Ciceronis Rhetoricam provides a representative example of this complexity, making available new conceptual material to reconstruct the sources of the medieval discussions about time and durations.
