Indibilis and Mandonius (fl. 3rd century BC) were
chieftains of the
Ilergetes, an ancient
Iberian (pre-Roman) people of the
Iberian Peninsula.
Polybius speaks of the brothers as the most influential and powerful of the Spanish chieftains in that time period.
Livy calls one of the chieftains of the Ilergetes "Indibilis", while Polybius gives "Andobales" for the same person. They agree that his brother chieftain was Mandonius.
