Note 4 at Ac 28:15: Appii forum (also called Forum of Appius or Forum Appii) was a small town, not much more than a travelers' stop, located about forty miles south of Rome on the famous Appian Way. Horace wrote of Appii forum, saying it was an unsavory place crammed with boatmen, innkeepers, and wayfarers, who cheat, carouse, and quarrel. This was one of the places where the Roman Christians came to meet Paul as he journeyed toward Rome.

Note 5 at Ac 28:15: Three Taverns was a small stop on the Appian Way, located about ten miles south of Rome and twenty miles north of Appii forum (see note 4 at this verse). Christians from Rome met Paul there as he traveled toward Rome.
