Catalogue Note

The collation of this copy differs from the one listed in VD17, by having two unnumbered leaves bound after D6 and not at the end.

This book, written by Galgemair and seen through the press by Brentel in 1610, deals with both the proportional compass and the sector. In the introduction, Brentel states that in recent years two works on the proportional compass have appeared: one by Levinus Hulsius, written in German (1604, lot 290); the other by Phillipp Horcher, written in Latin (1605, lot 286). While these works explained how to use the instrument, they do not show how to build and mark it. Brentel goes on to say that he did not personally possess sufficient knowledge to remedy this shortcoming and that in 1608 he sought out Georg Galgemair with whom he was acquainted and asked him to prepare a description of the instrument in German. Brentel goes on to note that using Galgemair's information, one is able to build a proportional compass in a few hours.
