Years from the conquest of Spain by Julius Caesar, in 38 BC.
King Don Ferrando succeeded to the states of Castille after the death of his father King Don Sancho el Mayor, in the aera 1072, which was the year of the Incarnation 1034, and from the coming of the Patriarch Tubal to settle in Spain 3197, and from the general deluge 3339, and from the creation of the world 4995, according to the computation of the Hebrews, and from the beginning of the false sect of the Moors 413.
Nothing more, owing to their default, can we say of this so notable a siege, than that when Don Cabrian, the Bishop of Leon, was earnestly engaged in prayer for the success of the Christian arms, the glorious St. Isidro appeared unto him, and certified that in fifteen days the city should be surrendered; and even so it came to pass, for the gates were opened to the King on Thursday the twenty-fifth of May, in the year of the aera 1123, which is the year of Christ 1085.
And one month he was practising with the Moors that he might keep them quiet, till Abeniaf was delivered into his hands; and thus ten months were fulfilled, and they were fulfilled on Thursday the last day of June, in the year of the aera one thousand one hundred and thirty and one, which was in the year one thousand ninety and three of the Incarnation of our Lord Jesus Christ.
