Thus I was; in the day the drought consumed me, and the frost by night; and my sleep departed from mine eyes. In the day the drought consumed me, and the frost by night - The being exposed to the heat by day, and frost by night, is made part of the heaviest punishment of Promethus by Aeschylus.
Σταθευτος δ' ἡλιου φοιβῃ φλογι, Χροιας αμευψεις· ασμενῳ δε σοι
Ἡ ποικιλεμων νυξ αποκρυψει φαος·
Παχνην θ' ἑῳαν ἡλιος σκεδᾳ παλιν.
Aeschyl. Prom. Vinc., v. 22.
Opposed to the sun's most fervid beam, The hue of beauty changed; till parch'd by heat The night with spangled stole shall hide its light From thee rejoicing, but again the sun Chases the hoar frost from thy harass'd form - J. B. B. C.
