Aeschylus, Agamemnon 1–8.

Extract

As is well known, many editors, following Valckenaer, reject the bracketed line altogether; but the omission leaves the opening clause with a very unsatisfactory ending. Ἐμπρέποντας αίθέρι, heavily stressed by its position, seems to form little less than an anticlimax, unless we assume that the stars could hardly be expected to shine in the sky. On the other hand, when line 7 is added, έμπρέποντας αίθέρ στέρας brings out clearly the fact that only certain conspicuous stars or constellations are meant—those which serve as guides to the operations of agriculture and navigation, such as the Pleiades, Arcturus, and Orion, as we may see from Hesiod, Op. 609 onwards.
