Editing Conon of Samos (section)

===Astronomical work===
In astronomy, Conon wrote in seven books his ''De astrologia'', including observations on solar eclipses. Ptolemy further attributes seventeen "signs of the seasons" to Conon, although this may not have been given in ''De astrologia''. Seneca writes that "Conon was a careful observer" and that he "recorded solar eclipses observed by the Egyptians",<ref>[[Otto E. Neugebauer]] (1975)</ref> although the accuracy of this statement is doubted. The Roman [[Catullus]] writes that Conon "discerned all the lights of the vast universe, and disclosed the risings and settings of the stars, how the fiery brightness of the sun is darkened, and how the stars retreat at fixed times."<ref>[[Ivor Bulmer-Thomas]] (1970-1990)</ref>
