Description

A sample of Johanes Hevelius' astronomical clocks. Some are presented broken down, as if in the process of repair or alignment.

Plate 18 from Johannes Hevelius’ Machinae coelestis pars prior…, Vol. 1.

Inscribed below: ‘A. Stech Delin I. Saal Sculps’

Johannes Hevelius (1611-1687) Polish astronomer was elected a Fellow of the Royal Society in 1664. He devoted much of his life to constructing astronomical instruments and, as time measurement became increasingly important to the study of astronomy in the 1600s, helped to develop a precision clock.

Object history

The Royal Society possess a copy of Volume 1 of Machinae coelestis pars prior… only. Volume 2 is rare, as many copies were burned in the fire of Hevelius' home and observatory in 1679.
