| 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. | ||||||||||
