Samothrace in the New Testament
Samothrace was in the Aegean. A conspicuous landmark to sailors; in Paul's first voyage to Europe from Troas to Neapolis (Acts 16:11). He sailed with a fair wind in going, so that his voyage took him only parts of two days, anchoring for the night at Samothracia, but in returning five (Acts 20:6). The ancient city, and probably the anchorage, was on the N. side sufficiently sheltered from a S.E. wind; this wind would counteract the opposing current which sets S. from the Hellespont, and E. between Samothracia and the mainland.
