Description

This 18th-century compass/ perpetual calendar, housed in ivory, could either be a “gadget cane” topper or a part of an optical and/or timekeeping compendium. For the first task, it just needs a flat thick screw to attach from the top of the small screw-off section of the two smaller lower parts of the main body, and a cleanly cut-off walking cane. Or, it could be connected to a Galilean telescope with an internal “fleaglass” microscope compendium, as of the kind typical to the early 18th century.

Chip to ivorine side with a flake broken off as shown.  A vertical crack running down next to the chipped piece is shown. The threaded top and bottom part all screw well into the threaded main body.  The compass and the perpetual calendar both work fine. The original needle, cover glass, and brass circlip ring are preserved.   Please see the photos for dimensions and condition.

IL Gilgamesh

Gilgamesh was the mythological hero of the cultures of ancient West Asia, who set out on a journey in which he sought youth and eternal life.
Fleaglass Gilgamesh is located in Israel. As an archaeologist researching the material culture of the distant past and using the microscope as a major research tool, for more than two decades I have collected microscopes from the first 300 years of existence of this amazing tool and researched the cultural context of their use. Passion has become an obsession and I cultivate the full and almost unique West Asian collection of historical microscopes. Respectively, I put up for sale surplus or interesting items from the collection. I would be happy to advise any interested collector free of charge. Needless to say, I would love to send photos, information and bibliographic references, and discuss the sale details of the items offered here for sale.
