Note Dry Dust, born brother to the Mire of war — THE AGAMEMNON
Gilbert Murray translation
[P. 21, l. 495, Dry dust, own brother to the mire of war.]—i.e. “I can see by the state of his clothes, caked with dry dust which was once the mire of battle, that he comes straight from the war and can speak with knowledge.” The Herald is probably (though perhaps not quite consistently) conceived as having rushed post-haste with his news.
