BIRTHA
(MESOPOTAMIA)
Birtha
was an ancient fortress on the river Tigris, which was said to have
been built by Alexander the Great. It would seem, from the description
of Ammianus, to have resembled a modern fortification, flanked by
bastions, and with its approaches defended by out-works. Shapur
II here closed his campaign in 360, and was compelled to retire
with considerable loss. D'Anville and Edward Gibbon both identify
Birtha as modern-day Tikrit, Iraq.
The
word "Birtha" in Syriac means a castle or fortress, and
might be applied to many places. From the known position of Dura,
it has been inferred that the remarkable passage of the Tigris by
Jovian in 363 took place near Tikrit. Towards the end of the 14th
century, this impregnable fortress was stormed by Timur. The ruins
of the castle are on a perpendicular cliff over the Tigris, about
200 feet (65 m) high. This insulated cliff is separated from the
town by a broad and deep ditch, which was no doubt filled by the
Tigris. At the foot of the castle is a large gate of brick-work,
which is all that remains standing; but round the summit of the
cliff the walls, buttresses, and bastions are quite traceable. There
are the ruins of a vaulted secret staircase, leading down from the
heart of the citadel to the water's edge.
