This paper uses a textual decision at Iliad 9.394 to argue for irregularity as a functional and meaningful principle in the constitution of the Homeric text. In contrast to almost all recent major editions, I argue that the ‘irregular’ MSS γαμέσσεται should be preferred to the Aristarchaean conjecture γε μάσσεται. Aristarchus’ widely adopted emendation, I suggest, is the product of a drive towards standardization that is still operative in Homeric text-critical practice. This paper opposes that standardization with the evidence of ancient, perhaps pre-Alexandrian, responses to Iliad 9.394, in which the ‘irregularity’ of γαμέσσεται is embraced as an interpretive opportunity. The formal disruptions of γαμέσσεται, I propose, can be understood by locating them both within the immediate context of Iliad 9 and within the wider thematics of irregularity that mark the character of Achilles. This paper thus attempts to reframe our approach to the role of irregularity in the Iliad as an integral feature of meaning rather than grounds for suspecting the integrity of the text.
