They are mentioned asLebékioi (Λεβέκιοι) byPolybius (2nd c. BC),[1]Libui byLivy (late 1st c. BC),[2]Libii andLibiciorum byPliny (1st c. AD),[3] and asLibikō̃n (Λιβικῶν) byPtolemy (2nd c. AD).[4][5]
According toPatrizia de Bernardo Stempel, the ethnonymLibikoi could derive from an earlier*lubhikoi ('the loving ones'; fromGaulishlubi 'love') with pretonic vowel assimilation (u...i >i...i).[6]
A homonym tribe is documented in northern Italy (seeLibicii (Cisalpine Gaul)). This may be the result of migrations from southern France.[7]
