Now Theophrastos stated that Diogenes of Apollonia borrowed some of his views from Anaxagoras and some from Leukippos, which must mean that there were traces of the atomic theory in his work. Further, Diogenes is parodied in the Clouds of Aristophanes, which was produced in 423 B.C., from which it follows that the work of Leukippos must have become known before that date. What that work was, Theophrastos also tells us. It was the Great Diakosmos usually attributed to Demokritos. This means further that what were known later as the works of Demokritos were really the writings of the school of Abdera, and included, as was natural, the works of its founder. They formed, in fact, a corpus like that which has come down to us under the name of Hippokrates, and it was no more possible to distinguish the authors of the different treatises in the one case than it is in the other.
