_c_) Capps[116] has plausibly suggested that knowledge of Epicharmus’ achievements in comedy was brought to Athens by Aeschylus, who is known to have been in Sicily _ca._ 476 B.C., shortly after 472 B.C., and for about two years before his death there in 456 B.C. _d_) The third actor was introduced into tragedy between about 468 and 458 B.C., and it is more probable that the use of three actors in comedy was borrowed from tragedy than vice versa. _e_) Cratinus won his first victory at the City Dionysia of 452 B.C. and (_f_) Crates at that of 450 B.C. Doubtless the activity of both men began somewhat earlier. _g_) It is incredible that the state should have postponed official control of comedy at the Lenaean festival until about 442 B.C., if the developments which we have been sketching had taken place long before. _h_) The earliest comedian to refer to Megarian comedy is Ecphantides, whose first victory was won between 457 and 453 B.C. Whenever Aristophanes “names any writers of ‘vulgar comedy’ who used the stale antics which he repudiates, these writers are his own predecessors and contemporaries of the Attic stage.”[117] This implies that the borrowing was a fairly recent occurrence. _i_) Finally, Megara was actually under the sway of Athens during 460/59-446/45 B.C. The opportunity for the exchange of ideas between Megara and Athens would naturally be most favorable at that time. In view of the preceding considerations, I am of the opinion that actors were introduced into Athenian comedy shortly before 450 B.C.
