When construction initially began on my quadrant, I had little to go on except the etching of the instrument and my own knowledge of how such an instrument should work. I knew the image came from a work of Tycho Brahe’s, Astronomiae Instaurate Mechanica (Instruments for the Restoration of Astronomy), but at the time was unable to find a translation to see if there was anything I was missing.
Fortunately, a few months ago, I finally located a translation of the vast majority of the book. However, the website seemed to lack the beautiful etchings that should accompany the text. However, scans of the original work were available through the NASA ADS. Unfortunately, being scans of a book over 400 years old, not all of the images were in good condition.
Still, I have worked to piece the text back together with the images, working over the past few months to digitally clean the images, removing smudges and stains, and reproducing the text as a digital copy best matching the original format as possible.
I now provide it as a .pdf for those interested.
