Καὶ τῆς Ἀρχελάου δ’ ἐπιθέσεως Δεκάμνιχος ἡγεμὼν ἐγένετο, παροξύνων τοὺς ἐπιθεμένους πρῶτος· αἴτιος δὲ τῆς ὀργῆς ὅτι αὐτὸν ἐξέδωκε μαστιγῶσαι Εὐριπίδῃ τῷ ποιητῇ· ὁ δ’ Εὐριπίδης ἐχαλέπαινεν εἰπόντος τι αὐτοῦ εἰς δυσωδίαν τοῦ στόματος.
(Aristotle, Poet. 1311b13)
Also Decamnichus took a leading part in the attack upon Archelaus, being the first to stir on the attackers; and the cause of his anger was that he had handed him over to Euripides the poet to flog, Euripides being angry because he had made a remark about his breath smelling. (tr. Harris Rackham)
