Elucidatio Fabricae Ususque Astrolabii by Johannes Stoeffler 1524

This is the 2nd edition of Elucidatio Fabricae Ususque Astrolabii, which describes the construction and use of Astrolabes. The title page, index, and the first 12 leaves are missing. This was considered to be the most influential Renaissance work on astrolabes, and also the first German work on astrolabes.
