About the moment
Medieval computists, the scholars who worked out the calendar and the date of Easter, used the moment as a small slice of the hour. The Venerable Bede described it in the 8th century. It was one fortieth of a solar hour, measured by the motion of a sundial shadow, and since the solar hour varied with the season, the moment was not fixed.
On average a moment equalled about 90 seconds, which is the figure used here. Bede's scheme also had the punctum at four per hour, the minutum at ten and the pars at fifteen, so a day held 960 moments. Bartholomeus Anglicus and Roger Bacon later wrote about the system, and Bacon subdivided the moment into 12 ounces of 47 atoms each. The modern phrase a moment is much looser, and the ostent that Bacon mentioned is seen as a forerunner of the modern minute.
