Reproduction of a "Diptych" sundial or pocket sundial inspired by the famous Spanish conquistador, Francisco Pizarro.
Compass dials, introduced in the 15th century, were the first portable shadow dials. The compass was used to point the quadrant northward and the gnomon (a piece of string or a folding triangle) was lowered or raised to adapt to the latitude at which the compass was used.
The golden age of sundials lasted from the 15th century to the end of the 18th century.
Supplied with an explanatory booklet.
