The History of the Decline and Fall of the Roman Empire - Edward Gibbon [1379]
[Footnote 71: The rubor of Domitian is stigmatized, quaintly enough, by the pen of Tacitus, (in Vit. Agricol. c. 45;) and has been likewise noticed by the younger Pliny, (Panegyr. c. 48,) and Suetonius, (in Domitian, c. 18, and Casaubon ad locum.) Procopius (Anecdot. c. 8) foolishly believes that only one bust of Domitian had reached the vith century.]
[Footnote 72: The studies and science of Justinian are attested by the confession (Anecdot. c. 8, 13) still more than by the praises (Gothic. l. iii. c. 31, de Edific. l. i. Proem. c. 7) of Procopius. Consult the copious index of Alemannus, and read the life of Justinian by Ludewig, (p. 135 - 142.)]
[Footnote 73: See in the C. P. Christiana of Ducange (l. i. c. 24, No. 1) a chain of original testimonies, from Procopius in the vith, to Gyllius in the xvith century.]
I shall conclude this chapter with the comets, the earthquakes, and the plague, which astonished or afflicted the age of Justinian. I. In the fifth year of his reign, and in the month of September, a comet ^74 was seen during twenty days in the western quarter of the heavens, and which shot its rays into the north. Eight years afterwards, while the sun was in Capricorn, another comet appeared to follow in the Sagittary; the size was gradually increasing; the head was in the east, the tail in the west, and it remained visible above forty days. The nations, who gazed with astonishment, expected wars and calamities from their baleful influence; and these expectations were abundantly fulfilled. The astronomers dissembled their ignorance of the nature of these blazing stars, which they affected to represent as the floating meteors of the air; and few among them embraced the simple notion of Seneca and the Chaldeans, that they are only planets of a longer period and more eccentric motion. ^75 Time and science have justified the conjectures and predictions of the Roman sage: the telescope has opened new worlds to the eyes of astronomers; ^76 and, in the narrow space of history and fable, one and the same comet is already found to have revisited the earth in seven equal revolutions of five hundred and seventy-five years. The first, ^77 which ascends beyond the Christian aera one thousand seven hundred and sixty-seven years, is coeval with Ogyges, the father of Grecian antiquity. And this appearance explains the tradition which Varro has preserved, that under his reign the planet Venus changed her color, size, figure, and course; a prodigy without example either in past or succeeding ages. ^78 The second visit, in the year eleven hundred and ninety-three, is darkly implied in the fable of Electra, the seventh of the Pleiads, who have been reduced to six since the time of the Trojan war. That nymph, the wife of Dardanus, was unable to support the ruin of her country: she abandoned the dances of her sister orbs, fled from the zodiac to the north pole, and obtained, from her dishevelled locks, the name of the comet. The third period expires in the year six hundred and eighteen, a date that exactly agrees with the tremendous comet of the Sibyl, and perhaps of Pliny, which arose in the West two generations before the reign of Cyrus.
