Brief Description: English 9' refracting telescope by John Marshall, London. Undated; c.1715.

Pasteboard tubes covered with vellum tooled in gold; lignum vitae lens mounts.
The effective aperture of the objective is 7/8".

The designs of the tools used for decorating this instrument are often found on Marshall's instruments. Their style is characteristic of the period 1700-1725. The coiled snake motif has not been recorded on bookbindings, and it is likely that body-tubes for telescopes and microscopes were made by a specialist, who sold them to the optical instrument makers who added the lenses.
