The first acknowledgment of the name Riccione, even if in an archaic form, appears within the Bavaro Code, a papyrus codex delivered by what it was known by the name of “Camera Arcivescovale ravennate” (Archbishop House of Ravenna) and that meticulously gathers  observations concerning the possessions and the donations of the ancient Church of Ravenna within the so called Pentapoli, a territory within which, during the Byzantine era, there was also the present-day municipality of Riccione. In the codex there are numerous references to the Arcioni area. The origins of the name, never verified, are various. Amongst them, the most evocative is surely Arkeion, a word of Byzantine origin linked to the name of a plant, the leppa, which grew along Riccione’s coast and was used as a medicine to cure hoarseness, coughs, ulcers and arthritis. The tradition of Riccione’s thermal baths had been already started.
