There were many ways in which the late medieval testator could acknowledge time. Behind each testator lay a lifetime of memories and experiences on which he or she drew, recalling the names of those ‘they had fared the better for’, those they wished to remember and by whom they wished to be remembered. Their present time was of limited duration, for at will making they had to assemble their thoughts and their intentions, make decisions and appoint stewards, as they prepared for their time ahead; but as they spent present time arranging the past, so they spent present time laying plans for the future. Some testators had more to bequeath, more time to spare: others had less to leave, less time to plan. Were they aware of time? How did they control the future? In an intriguing essay, A. G. Rigg asserts that ‘one of the greatest revolutions in man’s perception of the world around him was caused by the invention, sometime in the late thirteenth century, of the mechanical weight-driven clock.’ It is the intention of this paper to see how men’s (and women’s) perception of time in the late Middle Ages was reflected in their wills, the most personal papers left by ordinary men and women of the period.
