（*Dhmo/kritos), was a native of Abdera in Thrace, an Ionian colony of Teos. (Aristot. Cael. 3.4, Meteor. 2.7, with Ideler's note.) Some called him a Milesian, and the name of his father too is stated differently. (D. L. 9.34, &c.) His birth year was fixed hy Apollodorus in Ol. 80. 1, or B. C. 460, while Thrasyllus had referred it to Ol. 77. 3. (Diog. Laert. l.c. § 41, with Menage's note; Gellius, 17.21 ; Clinton, F. H. ad ann. 460.) Democritus had called himself forty years younger than Anaxagoras. His father, Hegesistratus,--or as others called him Damasippus or Athenocritus,--was possessed of so large a property, that he was able to receive and treat Xerxes on his march through Abdera. Democritus spent the inheritance, which his father left him, on travels into distant countries, which he undertook to satisfy his extraordinary thirst for knowledge.
He travelled over a great part of Asia, and, as some state, he even reached India and Aethiopia. (Cic. de Fin. 5.19; Strabo

(Polit. 8.6.) Again, a certain Androcles, to whom Cratinus and Telecleides often refer, was also attacked by Ecphantides, who could not, therefore, have flourished long before those poets. (Schol. Aristoph. Wasps 1182.)
The date of Ecphantides may be placed about Ol. 80 (B. C. 460), and onwards.
The meaning of the surname of *Kapni/as, which was given to Ecphantides by his rivals, has been much disputed, but it seems to imply a mixture of subtlety and obscurity.
He ridiculed the rudeness of the old Megaric comedy, and was himself ridiculed on the same ground by Cratinus, Aristophanes, and others. (Hesych. s. v. *Kapni/as; Schol. Aristoph. Wasps 151; Näke, Choeril. p. 52; Lehrs, Quaest. Epic. p. 23; Meineke, p. 36.)
