Read another anonymous work entitled _A Third Volume on the Holy
Easter Feast, in eight books_. The style is simple and very clear,
and contains many sensible ideas. In the fourth book the author
often refutes Metrodorus, and while supporting himself with evidence
from the Scriptures, works into his discussion of Easter some useful
remarks on the Creation by way of interpretation. It is dedicated to
one Theodore, whom he calls his beloved brother. He was the author
of other treatises on the same subject, but this is the fullest and
most useful, since he amply discusses everything bearing on the
subject. He gives a clear and detailed account of leap-year and the
intercalary month, the epacts of the sun and moon, the nineteen days
and the method of finding them, the months, the new moon, the week
and its days, which years are called cyclical and which intercalary.
He also discusses the twenty-eight years of the solar cycle, the
nineteen years of the lunar cycle and its fourteenth day, the lunar
and solar months, the new moon of the lunar and solar month, the
lunar month and the exact month, the calculation of the years of
the world. He says that according to the other years of His advent
our Lord and God Christ partook of the prescribed Easter feast, but
not on the day which was reported. This is worthy of consideration,
since Chrysostom and the Church teach that He partook of the regular
feast[596] before the mystic supper.
