Appii Forum

i.e., "the market of Appius" (Acts 28:15, R.V.), a town on the
road, the "Appian Way," from Rome to Brundusium. It was 43 miles
from Rome. Here Paul was met by some Roman Christians on his way
to the capital. It was natural that they should halt here and
wait for him, because from this place there were two ways by
which travellers might journey to Rome.
