Nocturnals

A nocturnal tells the time at night from the rotation of the stars around the celestial pole. The user sights Polaris through the central hole and turns a long pointer to align with the 'guard' stars of the Little Bear or the 'pointers' of the Great Bear. A calendar scale set to the date converts that angle to the hour.

Nocturnals were used from the sixteenth to the eighteenth century by navigators and travellers. Many are made of boxwood or brass, with tactile teeth on the hour disc so that the time can be counted in the dark.
