FORUM OF APPIUS ăp’ ĭ əs (τὸ̀ Αππίου φόρον, market of Appius). A traveler’s stop on the Appian Way forty-three m. S of Rome, where Paul was met by brethren from Rome on his way to the capital under guard (Acts 28:15).

It was also the northern terminus of a canal which ran through the Pontine marshes to Feronia, providing public transportation in boats towed by mules (Strabo 5.233). Horace (Sat. 1.5) vividly described the Forum as an unsavory place crammed with boatmen, innkeepers, and wayfarers, who cheat, carouse, and quarrel, the disturbance compounded by the gnats and frogs of the marshes.
