Δέρτρον

[Meaning the] peritoneum. But Aristarchus¹ [says it is] the skin and all the flesh over the liver. But better [to define it as] the beak. [We derive] de/rtron from the [verb] de/rein ["to skin"], which is to strike. With this vultures tear whatever they might eat with a strike of the beak. And this is a noun derived from a verb. As from plh/ssw ["I strike"] [comes] plh=ktron ["striker"], so from de/rw ["I skin"], [comes] de/rtron ["skinner"].
