The "Alexandrian Canon" compiled by Aristophanes of Byzantium and Aristarchus of Samothrace recognized Demosthenes as one of the ten greatest Attic orators and speech writers. According to Longinus, Demosthenes "perfected to the utmost the tone of lofty speech, living passions, copiousness, readiness, speed". Cicero acclaimed him as "the perfect orator" who lacked nothing, and Quintilian extolled him as "lex orandi" ("the standard of oratory") and that "inter omnes unus excellat" ("he stands alone among all the orators").
