Dragon-Well (עֶין הִתִּנַּין, eyn hat-tannin', fountain of the dragon; Sept. πηγὴ τῶν συκῶν) Vulg. fons draconis), the name of a fountain situated opposite or near the valley gate of Jerusalem (Ne 2:13). It is probably identical with the modern "Upper Pool of Gihon," on the north-western side of the city, and also with the "Serpent's Pool" mentioned by Josephus (War, V, 3:2). (See Strong's Harmony and Expos. of the Gospels, Append. 2, page 8.) SEE JERUSALEM.
