Notes on Ptolemy’s Analemma by Johannes Praetorius (1537-1616), instrument maker and professor of mathematics in Wittenberg (1571-1576) and Altdorf (1576-1616). The text is not attributed to Praetorius, but the only known MS is in his hand and looks like an author’s copy. Praetorius had probably access to Ptolemy’s text in Federico Commandino’s edition of 1562 (C.4.2).
