A good and nice example of a miniature diptych sundial made in wood and ivory and bearign the mark (a hand) of Leonhard Andreas Karner.
“Born in May 1782, he was the son of Georg Karner and great-grandson of Conrad II Karner. Has was known to be working in 1733. Hi maker’s marj was a hand” (Higton, Sundials in Greenwich, page 441).
The dial measures 4,2×3,1×1,2 cm, consisting in two leaves that fold flat when dial is not in use. Upper leaf I is completely ivory, lower leaf II has a wooden core.
The brass hinges are in good condition and the brass hook fastener is still present.
The compass preserved a part of is polychromy in red and blue.
The hand mark is on the lower face.
A nice miniature ivory dial from the latest compass-maker of the Karner family.
