Clement of Alexandria

The learned scholar Clement, presbyter of the church at Alexandria, regards the number of years as a matter of slight consequence, asserting that the seventy weeks of years were completed by the span of time from the reign of Cyrus, King of the Persians, to the reign of the Roman emperors, Vespasian and Titus; that is to say, the interval of four hundred and ninety years, with the addition in that same figure of the two thousand three hundred days of which we made earlier mention. He attempts to reckon in these seventy weeks the ages of the Persians, Macedonians, and Caesars, even though according to the most careful computation, the number of years from the first year of Cyrus, King of the Persians and Medes, when Darius also bore rule, up to the reign of Vespasian and the destruction of the Temple amounts to six hundred and thirty.

Daniel said there were 2, days from the time that the abomination of Nero stood in the holy city, till its destruction.… [This] makes six years and four months, during the half of which Nero held sway, and it was half a week; and for a half, Vespasian with Otho, Galba and Vitellius reigned.… After the 1, days … war ceased.
