The author's most important work. According to Gassendi, this work should be attributed more correctly to Tycho 

 Brahk, as the tables of celestial movements were begun under his direction, and executed after a treatise by him which 

 had been copied by Longomontanus. Important as the author's works were, he was much given to superstition (e. g. the 

 evil influence of coinet.s), and his circle-squaring problems turn up in his works as unexpectedly and persistently as King 

 Charles's head.
