Editing Democritus (section)

==Works==
Of the extent of his knowledge, which embraced not only natural sciences, mathematics, mechanics (Brandis, in the Rhein. Mus. iii. p. 134, &c.), grammar, music, and philosophy, but various other useful arts, we may form some notion from the list of his numerous works which is given by Diogenes Laertius (9.46-49), and which, as Diogenes expressly states, contains only his genuine works. The grammarian [[Thrasyllus]], a contemporary of the emperor [[Tiberius]], arranged them, like the works of Plato, into tetralogies. Unfortunately, not one of his works has come down to us, and the [[Pseudo-Democritus|treatise which we possess under his name]] is considered spurious. [[Callimachus]] wrote glosses upon his works and made a list of them;<ref>Suda, Democritus</ref> but they must have been lost at an early time, since even [[Simplicius of Cilicia|Simplicius]], writing in the 6th century AD, does not appear to have read them,<ref>Papencordt, de Atomicorum doctrina, p. 22</ref> and since comparatively few fragments have come down to us, and these fragments refer more to ethics than to physical matters.<ref>{{cite DGRBM|title=Democritus|url = https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0104%3Aentry%3Ddemocritus-bio-2}}</ref>
