Gomperz, _Griech. Denker_, i. p. 208; Heiberg, _Festskrift til Ussing_
(Copenhagen, 1900), p. 91; Decharme, p. 69.--Principal passages about
Diagoras: Sext. Emp. _adv. math._ 9, 53; Suidas, art. _Diagoras II._;

Aristoph. _Av._ 1071 with schol.; schol. Aristoph. _Ran._ 320; [Lysias]
vi. 17; Diod. xiii. 16 (the decree); Philodem. _de piet._ p. 89 Gomp.
(comments of Aristoxenus); Aelian, _v.h._ ii. 22 (legislation at
Mantinea).--Wilamowitz (_Textgesch. d. Lyr._ p. 80) has tried to save the
tradition by supposing that the _acme_ of Diagoras has been put too early.
Comp. also his remarks, _Griech. Verskunst._ p. 426, where he has taken up
the question again with reference to my treatment of it. As he has now
conceded the possibility of referring the legislation to the earlier date,
the difference between us is really very slight, and it is of course
possible, perhaps even probable, that the acme of the poet has been
antedated.--Aristoph. _Av._ 1071: "On this very day it is made public, that
if one of you kills Diagoras from Melos, he shall have a talent, and if
one kills one of the dead tyrants, he shall have a talent." The parallel
between the two decrees, of which the latter is of course an invention of
Aristophanes, would be without point if the decree against Diagoras was
not as futile as the decree against the tyrants (_i.e._ the sons of
Peisistratus, who had been dead some three-quarters of a century), that
is, if it did not come many years too late.--Wilamowitz (_Griech.
Verskunst, loc. cit._) takes the sense to be: "You will not get hold of
Diagoras any more than you did of the tyrants." But this, besides being
somewhat pointless, does not agree so well as my explanation with the
introductory words: "On this very day." On the other hand, I never meant
to imply that Diagoras was dead in 415, but only that his offence was an
old one--just as that of Protagoras probably was (see p. 39).

referring to the gods: _ibid._ B 4.--Plato: _Theaet._ p. 162_d_ (_Vorsokr._

Norvin's view of the theory of Protagoras.
