Rhodio, typically Roman, is an archaic form of the Rhodium surname that is typical of Puglia, of Guagnano in Leccese, of Locorotondo Nel Barese, of Martina Franca in Tarentino, of Ceglie Messapica and Ostuni in Brindisino, but it is well spread throughout the region outside the Foggiano, Rodia has a strain in Serino in the Avellinese and in Naples, and an Apulian in the Brindisino, Francavilla Fontana and Latiano, should derive from the Greek name?????? Ròdios or its Latin version Rhodius, we have an illustrious example in the erudite classical Greek writer Apollònios Ròdios (A????????? P?????) Rector of the Library of Alexandria in the III th century A. C., however, could also derive from the fact that he is the ancestor of the city of Rhodes, which is most likely for the Apulian strain: "Rhodianus, insulae Rhodi incula, qui Rhodius Rhodiensis, Rhodiacus Etiam dicitur.... ", difficult to hypothesize, even if not impossible, a derivation from the toponym Rodio in Salerno.
