THELUTHA
THELUTHA a fortress situated on an island in the Euphrates.
It is mentioned by Ammianus (24.2), who states that it was used as a treasury by the Persians.
It is unquestionably the same as the Thilabus of Isidorus (
Stathm. Parth. 1), who gives a similar description of it, and places it at no great distance from another island in the same river, Anatho. Zosimus, speaking of the same region, notices a fortified island, which he calls
φρούριον ὀχυρώτατον (3.15); probably the same place.
It is doubtless represented now by an island which Colonel Chesney calls
Telbes, Tilbus, or
Anatelbes (i. p. 53 and Map.).
