Carcase (πτωμα). As in Matthew 14:12, the corpse. Originally a fallen body from πιπτω, to fall, like Latin cadaver from cado, to fall. The proverb here as in Luke 17:37, is like that in Job 39:30; Proverbs 30:17.

Eagles (αετο). Perhaps the griffon vulture, larger than the eagle, which (Aristotle) was often seen in the wake of an army and followed Napoleon's retreat from Russia.
