However, it will occur that even this agreement is no positive evidence of the exactness of the time, for it may so happen that the sum-totals may agree, and yet every particular sum constituting the whole may be false, that is, if the quantity of errors which are too much exactly correspond with the quantity of errors that are too little; to obviate this as much as possible, I have considered three eclipses of the sun as recorded in the Abyssinian annals. The first was in the reign of David III. the year before the king marched out to his first campaign against Maffudi the Moor, in the unfortunate war with Adel. The year that the king marched into Dawaro was the 1526, after having dispatched the Portuguese ambassador Don Roderigo de Lima, who embarked at Masuah on the 26th of April on board the fleet commanded by Don Hector de Silveyra, who had come from India on purpose to fetch him; and the Abyssinian annals say, that, the year before the king marched, a remarkable eclipse of the sun had happened in the Ethiopic month Ter. Now, in consulting our European accounts, we find that, on the second of January, answering to the 18th day of Ter, there did happen an eclipse of the sun, which, as it was in the time of the year when the sky is cloudless both night and day, must have been visible all the time of its duration. So here our accounts do agree precisely. The second happened on the 13th year of the reign of Claudius, as the Abyssinian account states it. Claudius succeeded to the crown in the 1540, and the 13th year of his reign will fall to be on the 1553. Now we find this eclipse did happen in the same clear season of the year, that is, on the 24th of January 1553, so in this second instance our chronology is perfectly correct. The third eclipse of the sun happened in the 7th year of the reign of Yasous II. in Magabit, the seventh month of the Abyssinians. Now Yasous came to the crown in 1729, so that the 7th year of his reign will be in 1736, and on the 4th day of October, answering to the 8th day of the month Tekemt, N. S. in that year, we see this eclipse observed in Europe.
