In the time of
Alexander, and probably many ages afterwards, it was thinly inhabited
by a savage people of Icthyophagi, or Fishermen, who knew no arts, who
acknowledged no master, and who were divided by in-hospitable deserts
from the rest of the world. (See Arrian de Reb. Indicis.) In the twelfth
century, the little town of Taiz (supposed by M. d'Anville to be the
Teza of Ptolemy) was peopled and enriched by the resort of the Arabian
merchants. (See Geographia Nubiens, p. 58, and d'Anville, Geographie
Ancienne, tom. ii. p. 283.) In the last age, the whole country was
divided between three princes, one Mahometan and two Idolaters, who
maintained their independence against the successors of Shah Abbas.

As soon as the ambitious mind of Artaxerxes had triumphed ever the
resistance of his vassals, he began to threaten the neighboring states,
who, during the long slumber of his predecessors, had insulted Persia
with impunity. He obtained some easy victories over the wild Scythians
and the effeminate Indians; but the Romans were an enemy, who, by their
past injuries and present power, deserved the utmost efforts of his
arms. A forty years' tranquillity, the fruit of valor and moderation,
had succeeded the victories of Trajan. During the period that elapsed
from the accession of Marcus to the reign of Alexander, the Roman and
the Parthian empires were twice engaged in war; and although the whole
strength of the Arsacides contended with a part only of the forces of
Rome, the event was most commonly in favor of the latter. Macrinus,
indeed, prompted by his precarious situation and pusillanimous temper,
purchased a peace at the expense of near two millions of our money; [37]
but the generals of Marcus, the emperor Severus, and his son, erected
many trophies in Armenia, Mesopotamia, and Assyria. Among their
exploits, the imperfect relation of which would have unseasonably
interrupted the more important series of domestic revolutions, we shall
only mention the repeated calamities of the two great cities of Seleucia
and Ctesiphon.

Seleucia, on the western bank of the Tigris, about forty-five miles
to the north of ancient Babylon, was the capital of the Macedonian
conquests in Upper Asia. [38] Many ages after the fall of their empire,
Seleucia retained the genuine characters of a Grecian colony,
