During the Middle Ages, time, as now, was a major preoccupation. On
the other hand, the concept of time, as well as its measurement, was vastly
different. We think in split seconds, they thought in centuries, even millennia.
As the French medievalist Jacques Le Goff has so elegantly described it, there
was church time, merchant time, and work time; each had its own measure and
meaning. Religious feasts, for example, were moveable, the exact time of their
celebration determined by a phase of the moon; accurate, predictive calendars
were essential, since the dates for observance were set by law. For merchants,
time had a quantitative element, and calendars, at least daily calendars,
were also necessary; the amount of a debt to be paid depended on the number
of days the debt had been owed; its amount increased directly as the time
elapsed grew. The laborer's day had a still different measurement: it was
the time, not the wage, that was flexible. The workday extended from the hour
of Terce to the hour of None, which, practically, could be anywhere from six
to ten hours, depending on the season.
