Publisher's Synopsis
Excerpt from The Illustrated Account Given by Hevelius in His "Machina Celestis" Of the Method of Mounting His Telescopes and Erecting an Observatory: Reprinted From an Original Copy With Some Remarks
Upon all the works published by Hevelius he spared neither time, money, nor expense in their typography and' illustration. The engravings relating to the three selected chapters are proof of this; and having first photographed them, I have had them reproduced by a permanently printing process.
In copying these plates I have very much reduced their size, and I think they may be considered to be interesting as illustrating the precise method which he adopted in taking his observations, as well as his attitude and personal appearance.
