Great obscurity hangs over the chronology here indicated. According to Usher, the Smyrnaians began the month Xanthicus on the 25th of March. But the seventh day before the Kalends of May is the 25th of April. Some, therefore, read Aprilliwn instead of Maiwn. The great Sabbath is that before the passover. The "eighth hour" may correspond either to our 8 A.M. or 2 P.M.
