Nocturnal, by Amerigo Leonae, 1589
Combined nocturnal, lunar volvelle and Rojas projection. This instrument is more of a compendium than a pure nocturnal, but the shape shows that it was mainly used as a nocturnal. The Rojas projection allows it to be used as a sundial, and the inclusion of a lunar volvelle means that it could have been used as a moon dial. So this is a combined device to determine the time and the position at sea
