Medieval Scientific and Philosophical Instruments
(Spring 2000)

Introduction: For this workshop I have brought instructions and materials for you to make three different instruments typical of the Medieval period. But before we begin I would like to show you some instruments I have made, and discuss briefly some of the techniques I have used in making them, and relate how my methods compare to techniques current in the late Medieval period. You will find additional details about these instruments and techniques on my web-site.

I have brought a number of instruments that I have made over the years for your inspection: a navigational astrolabe, a planispheric astrolabe, and a torquetum (see the instrument page on my web-site). All of these instruments are fabricated from copper and/or copper alloys. I did not bring my cross-staff or armillary sphere because they are currently on display at the HSU Natural History Museum in their Millenium window display.

Projects. Three simple projects were constructed during this workshop. These projects are illustrated along with instructions for construction and sample calculations via the links below:
