Here is an attempt to identify the astronomical instruments on those pictures (I will label the top pictures with 1 through 4)
- This is an Armillary sphere;
- Instrument to measure altitude angles, similar to a Quadrant;
- Unsure! Maybe a flat Astrolabe?
- Unsure! Instrument to measure azimuth angles?
Hope others will chime in. Awolf002 15:30, 17 February 2006 (UTC)
