Perimedes and Eurylochus held the sheep,
our sacrificial victims, while I unsheathed
the sharp sword
The sheep - this is an example of the use of appositive in which "our sacrificial victims" stands for the sheep.
Quotation proving the answer (sheep) is correct.
"When I had prayed sufficiently to the dead, I cut the throats of the two sheep and let the blood run into the trench, whereon the ghosts came trooping up from Erebus- brides, young bachelors, old men worn out with toil, maids who had been crossed in love, and brave men who had been killed in battle, with their armour still smirched with blood; they came from every quarter and flitted round the trench with a strange kind of screaming sound that made me turn pale with fear."
The Odyssey/ Book 11
