Fragments of St. Anatolius of Laodicea

Nor is this an opinion confined to ourselves alone. For it was also known to the Jews of old and before Christ, and it was most carefully observed by them. And this may be learned from what Philo, and Josephus, and Musæus have written; and not only from these, but indeed from others still more ancient, namely, the two Agathobuli, who were surnamed the Masters, and the eminent Aristobulus, who was one of the Seventy who translated the sacred and holy Scriptures of the Hebrews for Ptolemy Philadelphus and his father, and dedicated his exegetical books on the law of Moses to the same kings. These writers, in solving some questions which are raised with respect to Exodus, say that all alike ought to sacrifice the Passover after the vernal equinox in the middle of the first month. And that is found to be when the sun passes through the first segment of the solar, or, as some among them have named it, the zodiacal circle.
