As the three ambassadors and the two heralds proceed toward the shelter of Achilles, a series of dual forms is activated in the narrative, starting already with the very first verse and continuing from there: 182, 183, 185, 192, 196, 197, 198. The intervening plurals as at 186 are negligible, since plurals can normally substitute for duals in Homeric diction. But duals cannot substitute for plurals. So, the problem is, who are the referents in these contexts where the dual form is used? One way to approach the problem is to follow through on the formulation of Nestor, who had said that Phoenix must lead the embassy, I.09.168, followed by Ajax and then by Odysseus, I.09.169. See the comment on I.09.167–170. But then, when the group reaches the shelter of Achilles, it is said explicitly that Odysseus now takes the lead, I.09.192. Further, when Ajax signals to Phoenix at I.09.223, it is Odysseus who picks up the signal instead, as indicated by the verb noeîn ‘take note (of), notice’ (see further the comment on I.09.223), and now it will be Odysseus and not Phoenix who delivers the first of the three speeches. At I.09.224, Odysseus fills a goblet with wine and toasts Achilles—a gesture that may have seemed more appropriate for Achilles to perform as the host, not for Odysseus as the guest. For Odysseus to violate the etiquette is not to violate the traditions of myth, however, in that it is traditional for the figure of Odysseus to violate rules of etiquette. At O.08.475–476, to cite another example, Odysseus seems to be behaving like a host in a situation where he is really the guest. For more on this point, see HQ 142. In any case, right after pouring the wine and toasting Achilles, Odysseus starts at I.09.225 to deliver the first of the three speeches addressed by the three ambassadors to Achilles. Only after this speech of Odysseus, I.09.225–306, and after the reply of Achilles to that speech, I.09.308–429, will Phoenix get a chance to give his own speech, I.09.434–605—even though Nestor had intended for Phoenix to be the first speaker. So, returning to I.09.192, where Odysseus already takes the lead away from Phoenix, we can view this point in the narrative as the marker of a transition: before this point, the dual forms could refer to Ajax and Odysseus, as led by Phoenix, but then, after this point, the dual forms could refer to Phoenix and Ajax, as led by Odysseus. Alternatively the dual forms in these verses could have an elliptic function, where a singular X is paired with a group Y. This way, the dual still refers to a pair, even though the second part of the pair is a group.
