Dercyllides
Dercyllides was an ancient Greek Platonist philosopher. There survive only quotations or paraphrases of his work in later writers, no complete works.
He is known to have to arranged Plato's works into tetralogies, similar to the edition of Thrasyllus of Mendes, whose arrangement is still used today. Whether Dercyllides or Thrasyllus came first is not known, however.
