sundial

Another way of telling the time was by using a sundial. In Tudor times almost all clocks worked using pendulums. Pendulum clocks need to be still and upright to work properly. They would not work on a moving ship.

Since watches hadn't been invented, the only portable way of telling the time was the pocket sundial.

Nine sundials were found on the Mary Rose, six of them looked like the one in the picture. This type are made of boxwood.

These sundials were probably made in Germay, in a city called Nuremburg.
