From this we should conclude that this comet must have been seen, however rapidly it did move, some time before the 6th of November, or two days before the feast of St Michael. But this depends on the circumstances of the climate; for though the tropical rains cease the first of September, the cloudy weather continues all the month of October; at the end of these fall the latter rains in gentle showers, which allay the fevers in Dembea, and make the country wholesome for the march of the army, and these rains fall mostly in the night. From this it is probable that the comet, having at first little light and no tail, as yet at a distance from the sun, was not very apparent to the naked eye, till by its increased motion and heat it had acquired both tail and brightness, as it approached its perihelion. Now we find by our European accounts[63], that, in the year 1689, there did appear a comet, the orbit of which was calculated by M. Pingrè. And this comet arrived at its perihelion on the 1st day of December 1689, so was going down much inflamed, and with a violent motion to the sun, the 6th of November, when it was observed at Gondar, being but 25 days then from its perihelion. As these circumstances are more than sufficient to constitute the identity of the comet, a phænomenon too rare to risk being confounded with another, we may hardly conclude the 9th year of Yasous the First to be the year 1689 of Christ, such as our chronology, drawn from the Abyssinian annals, states it to be; or, at least, if there is any error, it must be so small as to be of no sort of consequence to any sort of readers, or influence upon the narrative of any transactions. The 10th year began with a sudden and violent alarm, which spread itself in an instant all over the kingdom without any certain authority. The Galla with an innumerable army were said to have entered Gojam, at several places, and laid waste the whole province, and this was the more extraordinary, as the Nile was now in the height of its inundation. On his march, the king learned that this story arose merely from a panic; and this formidable army turned out no more than a small band of robbers of that nation, who had passed the river in their usual way, part on horseback, while the foot were dragged over, hanging at the horses tails, or riding on goats skins blown up with wind. This small party had surprised some weak villages, killed the inhabitants, and immediately returned across the river. But the alarm continued, and there were people at Gondar who were ready to swear they saw the villages and churches on fire, and a large army of Galla in their march to Ibaba, at the same time that there was not one Galla on the Gojam side of the river.
