Description

The Austrian maker Simon Georg Plössl made these Galilean telescopes before 1738. In many cases, they were signed “Plössl in Wien,” but there are some known examples, such as this one, of unsigned instruments. Similar telescopes signed by Plössl in Wien van be seen on the following links:

The front lens is an achromatic doublet, and the four eyepieces on the revolver are negative focus singlets. 

The telescope is generally in good condition with age scratches on the gilded brass. The blackened handle covering the screw (optionally used to attach the telescope to a wooden base) has a crack, but it is stable. One lens in the eyepiece revolver is damaged. These issues are shown in the photos in detail. The offering price considers these issues. This is a rare early telescope of a significant European instrument maker who later developed the Plössl ocular for telescopes, which is still used today.

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.
