Troas in Easton's Bible Dictionary

a city on the coast of Mysia, in the north-west of Asia Minor, named after ancient Troy, which was at some little distance from it (about 4 miles) to the north. Here Paul, on his second missionary journey, saw the vision of a "man of Macedonia," who appeared to him, saying, "Come over, and help us" (Acts 16:8-11). He visited this place also on other occasions, and on one of these visits he left his cloak and some books there (2 Cor. 2:12; 2 Tim. 4:13). The ruins of Troas extend over many miles, the site being now mostly covered with a forest of oak trees. The modern name of the ruins is Eski Stamboul i.e., Old Constantinople.
