The brass shepherd's clock

The shepherd's clock

It is likely that the monk of Reichenau, Hermann the Lame (1013 - 1054), developed this type of sundial. They were very popular during the Middle Ages because they were robust and did not require a compass.

1) Turn the horizontal arm of the cross to the month (J for January; D for December).

2) Orient the clock in the direction of the sun. The tip of the shadow will show you the WOZ (true local time) on the next engraved curve leading to the hour numbers - morning hours on the left, afternoon hours on the right. Supplied with a strap.
