29. Earliest date

The impressive scope of the Grand Saros Canon and of the Saros scheme in general does not insure the validity of individual entries. The four earliest dates are computed from the text of tablet shard LBAT 1413. The preserved text is insufficient to determine a unique set of dates for these eclipses. At least one historian hesitated to ratify Feb 6, 747 BC as the earliest date recorded in a Saros.
