My Four Questions:
1) Was the astrolabe rare and expensive or common and more widespread?
2) Was the astrolabe used in only one profession, or did it serve numerous kinds of occupations?
3) Who was it who constructed astrolabes, and when were they first built?
4) Did the astrolabe develop as time went on, or did it remain the same from the start of its prominence to the end?
