" In 1846 on of his Academy exhibits was a painting called The Angel Standing in the Sun. Turner found this passage for the Academy catalogue in the Book of Revelation:

And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God; That ye may eat the flesh of kings, and the flesh of captains and the flesh of mighty men, and the flesh of horses, and of them that sit on them, both free and bond, both small and great.

To reinforce the note of voracious doom, he added two lines from Samuel Rogers' Voyage of Columbus:

The morning march that flashes to the sun;
The feast of vultures when the day is done. "
