We came with a straight course to Samothracia. — Their course lay to the north-west, and, probably, after the manner of the navigation of the time, they put into harbour each night; and the historian, with his characteristic love of geographical detail (see Introduction to St. Luke’s Gospel), notes the main facts of the voyage. The “straight course” implies that they had the wind in their favour. The current, which sets to the south after leaving the Hellespont, and to the east between Samothrace and the mainland, would, of course, be against them. In Acts 20:6, the voyage from Philippi to Troas takes five, days. The name of Samothrace points, probably, to its having been a colony from Samos. In early Greek history it had been one of the chief seats of the worship of the Pelasgic race, and, besides the mysteries of Demeter and Persephone, which it had in common with the rest of Greece, was celebrated for the local cultus of the Cabiri, a name of uncertain origin, and applied to the twelve great gods.
The next day to Neapolis. — The name (=new town) was naturally common wherever Greek was spoken. It survives in two conspicuous instances — in Naples, and in Nablous as the modern name of Sychem. The town now before us was in Thrace, about twelve miles from Philippi, which was the frontier town of Macedonia. It has been identified, on adequate grounds, with the modern Kavalla, where a Roman aqueduct, columns, and Greek and Latin inscriptions remain to attest the former importance of the city. Ten or twelve miles to the west are the traces of another harbour at Eski Kavalla, which was probably the Palæopolis (= old town) that had been superseded by the new port.
