Biography:Diodorus of Alexandria
Diodorus of Alexandria or Diodorus Alexandrinus was a gnomonicist, astronomer [1] and a pupil of Posidonius.[2][3][4]
Writings
He wrote the first discourse on the principles of the sundial, known as Analemma.[5] a commentary on this having later been written by Pappus of Alexandria,[6] that is no longer extant.[7] A small number of sentences having survived the centuries and attributed to him are known; these comment on: the differences between astronomy and natural science, the word meanings for cosmos and star, the nature of stars and the Milky Way. He was known to Eudoros. A few surviving passages might come from a commentary on Aratus. In his dealings with astronomy he was known to Marinus in his commentary on Euclid's Data containing quotes of Diodorus's opinions on the meaning of a term.[8]
