The Venetus A manuscript, like many others—including some of the oldest, such as the Venetus B and the Townley manuscripts—does not include the line that is canonically called 10.531: νῆας ἔπι γλαφυράς· τῇ γὰρ φίλον ἔπλετο θυμῷ (“toward the hollow ships; for this way was dear to them in their hearts”). According to Allen, thirty of the one hundred eighteen manuscripts he collated do not include this line. At Iliad 11.519–520, we see the same pair of lines that some manuscripts record as 10.530–531: in that context, it is Nestor and Machaon who depart the fierce battle after Machaon is wounded by the arrow of Paris. The presence of this line in some witnesses to Iliad 10 should caution us about overinterpreting the formula in either context. It is tempting in Iliad 11 to see the horses’ desire to go a certain way as relating to their desire to leave battle, or that heading toward the ships, toward home, is what makes the direction dear to their hearts. But in the context of Iliad 10, those same interpretations cannot apply to Rhesos’ horses, which have just arrived at Troy and are now under the control of new drivers or masters. Instead, we can understand it in both places, in conjunction with the horses “flew not unwillingly” (τὼ δ᾽ οὐκ ἀέκοντε πετέσθην), as a formula dealing with horses who are whipped and then respond by moving quickly in a particular direction.
