Seleucia
Collier's New Encyclopedia (1921)
the name of several ancient cities of Asia, situated in Assyria, Margiana, Syria, Mesopotamia, Cilicia, Pamphylia, Pisidia, Caria, and other countries, of which the following are the TIGRIS was founded by Seleucus I. of Syria, on the left bank of that river, near its junction with the royal canal of Babylonia, and opposite to the mouth of the Delas (now Diala) river, a little S. of the modern city of Bagdad. Commanding the plains of the Tigris and Euphrates and the principal caravan roads of Assyria and Babylonia, on the confines of it was situated, and peopled by which settlers from various countries of western Asia, it rapidly rose in wealth and splendor, and, eclipsing Babylon, became the capital of that part of Asia, till it was in its turn eclipsed by Ctesiphon, built by the Parthians on the opposite bank of the Tigris. The later wars of the Romans against that people proved destructive to Seleucia. A city of upward of 500,000 inhabitants in the 1st century, in the following it was burned by Trajan and Lucius Aurelius Verus, and captured by Septimius Severus, and in the expedition of Julian against the Persians, in the 4th century, was found deserted. (2) SELEUCIA PIERIA, a strong fortress of northern Syria, also founded by Seleucus I., whose remains were preserved there in a mausoleum, was built at the foot of Mount Pieria, on a rock overhanging the Mediterranean a few miles N. of the mouth of the Orontes, and W. of Antioch, with which it was simultaneously founded, and of which it formed the seaport. It surrendered to Ptolemy III. of Egypt, was recovered by An tiochus the Great, and in the latter pe riod of the Syrian kingdom became independent. Under the Romans it rapidly decayed. Considerable ruins of its harbor, fortifications, and necropolis are still to be seen.
What Has Changed in the Last Century
When Collier's wrote this in 1921 Seleucia on the Tigris was known almost entirely from Greek and Roman authors, and no one had dug it. Excavation began soon after: an American expedition from the University of Michigan worked at Tell Umar from 1927 into the 1930s, and an Italian mission from the 1960s uncovered an archive building whose burning had baked tens of thousands of clay seal impressions, giving direct evidence of the city's administration and trade. The site now lies within the sprawl of greater Baghdad, close to the surviving great arch at Ctesiphon, and has suffered from looting and encroachment. Seleucia Pieria, described as still showing "considerable ruins," is today Samandağ in Turkey's Hatay province, where the rock-cut Titus water tunnel is a visited monument; the province only passed from French-mandate Syria to Turkey in 1939.
