Note: The bones (a jaw and shin bones) "...dated from AD 61, when Boudicca's British tribes burnt down the town to try to free themselves from Roman rule."
Comment: Boudicca was queen of the Iceni, a British tribe which staged a major rebellion against the Roman occupation after various outrages and serious provocation. From what I've read, the Romans brought the revolt on themselves with their typically heavy-handed administration.
According to the Encyclopedia Britannica, "Boudicca’s husband, Prasutagus, was king of the Iceni (in what is now Norfolk) as a client under Roman suzerainty. When Prasutagus died in 60 with no male heir, he left his private wealth to his two daughters and to the emperor Nero, trusting thereby to win imperial protection for his family. Instead, the Romans annexed his kingdom, humiliated his family, and plundered the chief tribesmen." Boudicca was flogged and her two daughter were raped.
The novelist George Shipway described the revolt in his masterpiece, Imperial Governor, which, along with Eagle In The Snow by Wallace Breem, is one of the best novels about ancient Rome ever written. According to Shipway's scholarly and extremely well written account, the draconian recall of Iceni loans was official Roman policy, but the flogging of Boudicca and the rape of her daughters were the actions of one particularly idiotic Roman official responsible for the collection of the payments.
