Sorry, I need to make a correction. Viriato (Viriatus), was the leader of the Lusitanian people, and not leader of the Iberians. Viriato, lived mostly in the actual Serra da Estrela (Mountain Range Star), which is in fact Portuguese (old Lusitanian) territory, not Spanish. Most of the old Lusitanian territory is actual Portuguese land, so he was more of an ancient Portuguese (the Portuguese people can be called as Lusitanians even in the actuality), than an old Spanish

There were an Iberian leader called Viriato, in Spanish, who was murdered by order of Caesar, because he was still fighting against Rome.
He was killed by one of his men, bribed by the romans (well, in fact, he was never paid, when he went to take his money Caesar said "Rome doesn´t pay traitors")
I think his name in Latin could have been Viriatus, I am not sure
I hope this will help you.
