Navigating with the Stars and the Moon in the Elizabethan era...
This delicate instrument was specially made for a shipowner and is considered one of the first English Renaissance instruments. It is perfect to have in any collection.
It´s a reproduction of a Nocturnal dial and a Tides computer.
It was made by Humphrey Cole (1570), and the original piece is at the British Museum.
One of its faces is a Nocturnal and the other is a Tide Computer. The Nocturnal or star clock is an artifact that is used to obtain the time at night using the fixed stars in the sky. The abacus or tide computer is used to figure the time of the tides, which greatly affect navigation both in harbors and for fishing.
