iters, as
Alfergani, date from the 1st of September. At Tyre the year was counted
from the 19th of our October, at Gaza from the 28th of the same month,
and at Damascus from the vernal equinox. These discrepancies render it
extremely difficult to determine the exact correspondence of Macedonian
dates with those of other eras; and the difficulty is rendered still
greater by the want of uniformity in respect of the length of the year.
Some authors who follow the Macedonian era, use the Egyptian or vague
year of 365 days; Albategni adopts the Julian year of 3651/4 days.

According to the computation most generally followed, the year 312 of
the era of the Seleucidae began on the 1st of September in the Julian
year preceding the first of our era. Hence, to reduce a Macedonian date
to the common era, subtract 311 years and four months.

The names of the Syrian and Macedonian months, and their
correspondence with the Roman months, are as follows:--

Syrian. Macedonian. English.
Elul. Gorpiaeus. September.
Tishrin I. Hyperberetaeus. October.
Tishrin II. Dius. November.
Canun I. Apellaeus. December.
Canun II. Audynaeus. January.
Sabat. Peritius. February.
Adar. Dystrus. March.
Nisan. Xanthicus. April.
Ayar. Artemisius. May.
Haziran. Daesius. June.
Tamus. Panemus. July.
Ab. Loues. August.

_Era of Alexander._--Some of the Greek historians have assumed as a
chronological epoch the death of Alexander the Great, in the year 325
B.C. The form of the year is the same as in the preceding era. This era
has not been much followed; but it requires to be noticed in order that
it may not be confounded with the era of the Seleucidae.

_Era of Tyre._--The era of Tyre is reckoned from the 19th of October, or
the beginning of the Macedonian month Hyperberetaeus, in the year 126
B.C. In order, therefore, to reduce it to the common era, subtract 125;
and when the date is B.C., subtract it from 126. Dates expressed
according to this era occur only on a few medals, and in the acts of
certain councils.

_Caesarean Era of Antioch._--This era was established to commemorate the
vict
