The minute, as a measurement of time, didn’t exist.
During the Middle Ages, people used a combination of water clocks, sun dials, and candle clocks to tell time though none of those could tell time to the minute. While the best water clocks told time to the quarter hour, it wasn’t until the wide use and improvement of mechanical clocks that people could tell time to the minute.
For most of the Middle Ages, clocks rang seven or eight times in a day, not twenty-four.
The length of an hour depended on the time of year and where you lived.
You Couldn’t Waste Time (which supposedly belonged to Gawd), and Time Couldn’t Cost You Money.
Dante Alighieri made the first literary reference to clocks that struck the hours.
